These ground water areas are called aquifers. There are 22 DWP regulated aquifers south of the San Gabriel Mountains. Each of which is thoroughly monitored by its own governing agency. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594602649138-N9ERQ1ZNYQGO96DFW813/LA+Basin+Watershed Crawlspaces You’ve probably heard of the “LA Basin.” The San Gabriel Mountains contribute rainwater to LA area. The Santa Monica Mountains, Palos Verdes, Baldwin Hills and Signal Hill all contribute to moisture being added into the “LA Basin.” https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594831604696-VV2XG9VCXLAHLZXHYST9/crawlspace%2Bfans.jpg Crawlspaces - Crawlspace Fan Systems When cross ventilation isn’t sufficient, mechanical ventilation is required per building codes. Sophisticated sensors placed inside a crawl space and on the exterior of a home can govern a system of fans. All automatic, but with a digital monitor inside a home for peace of mind. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594830714806-G26RBXH7ZKSKYJTKWP2J/Water-Proofing_drawing1.jpg Crawlspaces However, a crawlspace that is situated below a french drain can be saturated with groundwater creating humidity, mold, and dry rot of the structural lumber that supports the home. This then is the starting place for termites to infest a home. When adding a french drain system lower than a crawlspace isn’t practical, an intelligent fan system is the best solution. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594832139423-ZZG46U51XLISMC2FY6UO/vapor+barrier.jpg Crawlspaces - Crawlspace Vapor Barriers Groundwater can be redirected by changing its path of least resistance. Covering the dirt in a crawlspace will cause groundwater to pass by a home and continue to a lower property. However, one should never cover the footings, since this obfuscates cracks and other foundation issues that develop over time. When covering the floor of a crawlspace the footings become more saturated because, more water is forced up the footings via capillary action. Capillary Action: the ability of a liquid to defy gravity in masonry. The most effective crawlspace system covers moist dirt with a vapor barrier, plus an intelligent fan system to dry out the footings. What isn’t passing under the house is being dried out. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594835008210-TNOTFPFOXFQIT0B851FC/07lg-cutaway-pump-diagram.jpg Crawlspaces Masters of Moisture has invented an ideal “soaking sump system” that allows water in while filtering out dirt and preventing penetration from roots. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594829816668-ZD3T4JTBH7NY5PJF7X97/termite-damage-foundation.jpg Crawlspaces - Termites: any of numerous pale-colored soft-bodied social insects that live in colonies consisting usually of winged sexual forms, wingless sterile workers, and soldiers. They feed on wood. All termites are very thin skinned, which is the reason humidity is very important for their comfort and survival. They would dry out quickly and die if they were exposed to the elements. Hence, termites love humidity. In fact, they seal up their colonies in order to preserve humidity within the colony. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594831793583-2J5PTD4WJ66P6OTAM596/ATMOX+What+is+in+your+crawlspace.png Crawlspaces An intelligent fan system brings air from outside your home only when it will soak up the moisture below. This is done by measuring dew point and ignoring Relative Humidity and Temperature. Dew Point: when air is chilled and releases it’s moisture as in dew in the morning. Crawlspace fans that merely measure humidity or temperature are in fact stupid. Hot air holds more moisture than cold air. When hot air is forced into a cool crawlspace it releases moisture more often than not. Fans controlled by a humidistat or a thermostat add moisture to crawlspaces. The Atmox Intelligent Fan Systems measure dew point with a rare tool called a dew-point-stat. When crawlspace moisture is extreme an intelligent fan system can include wood moisture sensors, and a dehumidifier. In this case two fans systems operate independent of each other. When air outside will only moisten the crawlspace the intake and exhaust fans are turned off and another set of fans along with a dehumidifier turns on. The fans circulate crawlspace air toward a dehumidifier that mechanically soaks up moisture and places it in a pipe to carry water outside the structure. With this system a crawlspace is being dehumidified 24/7/365, but only when experiencing unhealthy moisture levels. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594609018345-M18AE737P7T18T6G9RD4/structurally-damaged-wood-crawlspace-lg.jpg Crawlspaces - Dry Rot: wood decay occurring in poorly ventilated conditions in buildings, resulting in cracking and powdering of the wood. Wood that has over 20% moisture content is susceptible to dry rot which destroys its structural value. Still and humid conditions causes dry rot in crawlspaces. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594833100537-UTKT87DIUI6V25W0Y9J3/Crawl_Space_Leaks263-DFs.jpg Crawlspaces - Standing Water Solutions Homes built into hillsides or on the flat lands of valleys can have standing water or little creeks inside. When not visibly present evidence of such may exist. Sheet barriers and fan systems cannot handle standing water in a crawlspace. This condition requires a sump. sump: a pit in which liquid collects. Sumps usually need sump pumps to move the water collected away from a structure. Most sumps are manufactured in a way to collect surface water off a concrete floor. These do not work in a crawlspace due to the usual dirt floors. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594830340528-F6IVUTHFG38JMVZU3NKR/diagram-french-drain-300x288.png Crawlspaces - French Drains: an under ground drainage system. Ideally french drains are installed around the outside perimeter of a structure, however retrofitting this system after a building has been landscaped and outfitted with planters, concrete walkways and patios can often be cost prohibitive. Unfortunately homes that have french drains, have often been installed too high to be effective. Place a french drain well below the floor of a home and the home, itself, will be protected from flooding. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1594609385484-D5EEJW2MCJZ2UG08N5BZ/Crawlspace+mold.jpg Crawlspaces - Mold: a growth that degrades a cellular material. Mold requires humid conditions to form and continue to spread. Moisture content above 19% for approximately one week is required for significant surface mold growth to occur on structural building components. https://mastersofmoisture.com/slabs-1 daily 0.75 2025-10-07 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596519046811-3KWTTQRGMU016O7X7QAA/186828F1-FDCD-42D8-A485-56F97BAD2753.jpeg Slab Foundations Not all slabs have moisture barriers underneath and these can become compromised over time. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596163834929-6D1UM09YUI2AF7YUBSU7/concrete+sealed.jpg Slab Foundations All concrete soaks up water unless it’s been sealed. Properly sealed; water beads up and runs off.

It is 12-18% porous. Rain, irrigation and ground water soaks in from any direction. Concrete and porous tile patios and walkways next to a house soak up moisture and hold that water next to a house, often contributing to moisture problems in slab homes. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596163890612-Z916INCYM3J5HS4BQ5PE/source+of+water.jpg Slab Foundations Water that enters concrete is retained.

They must first be stripped back to bare concrete. Then one of several special materials is applied that soaks into concrete and crystalizes. Don’t be fooled by paint-on materials that claim to repel hydrostatic pressure such as Drylok. It covers the evidence of moisture intrusion for a short period of time and then bubbles and peels in a disappointingly few weeks. Applying materials to repel hydrostatic pressure must be done precisely and with the most appropriate materials for the condition. Professionally applied amateur materials or applications of professional materials by an amateur will not work. These will need to be removed before one can do the job effectively with professional materials. https://mastersofmoisture.com/mold daily 0.75 2025-10-07 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596771350284-1JA2HG5P55GJ4P1YGCJG/Mold-Testing-Lab-Interpretation.png Mold https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596778061459-O8J0Q7TFGPQ3CTKZ6LO1/mold+on+dirt+in+crawlspace.jpg Mold Dirt in a crawlspace can be a host to mold when that dirt is wet. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596777826145-VDUC802NPLRZA3O683X5/mold-under-carpet.jpg Mold Most carpet is synthetic, however carpet backings are not.

No meter can diagnose the cause of moisture intrusion. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1603582803013-C7SRV4CUS9UYI759V3VK/Picture1.png Inspections Moisture adds density. But how dense is a particular type of wood before it becomes moist? https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253045035-ZPME63C73HFZLCLMWRYV/Picture9.png Inspections https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253222193-QVCPFFJZI67LOHS83A0G/Picture11.png Inspections Concrete is 12-18% porous. It sheds rainwater when sloped properly, however becomes saturated in the process. Concrete soaks up groundwater as well. The day this slab was poured it registered at 6 (top of the scale). A dry slab would measure towards the bottom of the scale. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604252537012-JSSFXPGRYR4PDSHHNBC8/Picture2.png Inspections - SOFTWOODS There are countless species of “softwoods” and “hardwoods”… https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604252719798-3FJIIOXS60NL5QQ8L4AZ/Picture6.png Inspections Another trick to measuring wood floors is measuring only the wood and not what’s below it. Meters often measure up to 1 1⁄4” into a surface. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253410187-8VP08DS8KWVN8SD1ELTX/Picture14.png Inspections Humidity levels above 55% cause mold, dry rot and attracts termites, especially in crawlspaces with a lack of air circulation. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253379966-CS9VZPBGKK4PEFJKBYN0/Picture13.png Inspections Where ladders are not practical, drones can take a look above a building, or around the neighborhood. Quite often groundwater issues begin at a neighboring property. Drones can discover all kinds of moisture problems visible from above. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604252675020-AN72MUIUX582MFTLKYRV/image-asset.png Inspections Only familiarity prepares an inspector for the challenges of measuring moisture in building materials. This wood isn’t wet, but it’s so dense that it reads as though it is on this very professional meter. But it’s the wrong professional meter. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604252765802-62AX5SX3JS545BKQZTNE/Picture7.png Inspections When measuring a wood floor that’s only 1⁄2” thick you can be measuring the density of the concrete below, depending on your meter. For this reason a special meter can be adjusted to only read a shallow depth. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604252793153-5032RFLRYUP13Z3ZBTOW/image-asset.png Inspections Drywall, plaster, tile, concrete and roofs can be measured for moisture saturations. Specialty meters are the most accurate. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253626385-3LR3K8H0WY4JKL6ST3NI/image-asset.png Inspections Office buildings and well-built condos have an additional layer between ceilings and floors above. This makes finding leaks more difficult. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253710932-COKW0VNNR6CW1FMNCXSI/Picture18.png Inspections “Flat roofs” are required to have a 1⁄4” slope for every horizontal foot. This building code is seldom checked by building inspectors. And even if this requirement is met on the day it was build heavy equipment causes wood supports below to sag. This then causes pooling, which leads to leaks over time. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1604253581834-1XI4538KCE04Z0JRJ11I/Picture16.png Inspections Homes between an ocean and a mountain range are subjected to more humidity than homes in a valley or desert. https://mastersofmoisture.com/new-page daily 0.75 2025-10-07 https://mastersofmoisture.com/moisture-intrusion-faqs daily 0.75 2025-10-07 https://mastersofmoisture.com/contact-copy daily 0.75 2025-10-07 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1596758991785-FKXJ3L2T1KJA4TCBU3Q3/mold+zero.jpg Joining Us If you wish to reach Mold Zero call Raymond at ‭(747) 231-9371‬ https://mastersofmoisture.com/home-sales daily 0.75 2025-10-07 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/ff5e8a5f-932e-4a5c-a614-3af82e7d0736/HOME+SALES.png https://mastersofmoisture.com/privacy-policy daily 0.75 2025-10-07 https://mastersofmoisture.com/seminars daily 0.75 2025-10-07 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/27b3334e-a207-4fb5-bf21-b704e99895d3/IMG_4621.jpeg https://mastersofmoisture.com/propertymanagers daily 0.75 2025-10-07 https://mastersofmoisture.com/work daily 0.75 2025-10-07 https://mastersofmoisture.com/work/hillside-livingspace-moisture-intrusion monthly 0.5 2020-06-04 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589943776818-WJSK4YO7CX5BRO30N84C/CBC683B6-ECA9-4E45-8C4D-842CA328AE1E.JPG Work - Hillside Livingspace Moisture Intrusion More moisture intrusion through the masonry. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589943419006-XV2WRJI7N089UCG1PPAO/IMG_5385.jpg Work - Hillside Livingspace Moisture Intrusion Moisture Intrusion behind the walls. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589944148941-QAEOJEWOFW5GDER6BN16/331E9561-01BD-4583-AA38-6190E26E285E.JPG Work - Hillside Livingspace Moisture Intrusion https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589943460636-EBH5UHMXOXNB23ALGV8X/IMG_5405.jpg Work - Hillside Livingspace Moisture Intrusion Water damage and wood rot under the floor boards. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589944026667-1TO3SN4T2LLV0KCKYV3F/IMG_5406.jpg Work - Hillside Livingspace Moisture Intrusion https://mastersofmoisture.com/work/basement-ground-water-intrusion monthly 0.5 2020-05-20 https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589942086348-D4BKO8T2T3Y6XN6AJFGC/IMG_6488.jpg Work - Basement Ground Water Intrusion Room Below Grade https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589942171404-AFYHXIHQ1TVIPKB1K9CC/IMG_6516.jpg Work - Basement Ground Water Intrusion Evidence of long term moisture exposure in the basement crawlspace. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589942269081-MXUFREZCXAG1GGG88X3Q/IMG_6536.jpg Work - Basement Ground Water Intrusion Raw wood in contact with the ground in the crawlspace and water damaged. https://images.squarespace-cdn.com/content/v1/5ec46f020af9ec4b9f6fa8a6/1589942372686-BKTMVX3UJ3OZLOG3G2W5/IMG_6539.jpg Work - Basement Ground Water Intrusion Joists showing signs of water damage. https://mastersofmoisture.com/videos daily 0.75 2025-06-04 https://mastersofmoisture.com/videos/inspections monthly 0.5 2025-06-04 https://mastersofmoisture.com/videos/projects monthly 0.5 2025-06-04 https://mastersofmoisture.com/videos/tips monthly 0.5 2025-06-04 https://mastersofmoisture.com/videos/v/everything-to-sell-anything-427ge-88xsk-rt6mk monthly 0.5 2022-08-16
