Most states also require that local waterproofing contractors have workers' comp insurance covering all of their employees.

But that is no guarantee that any particular waterproofing company is doing business ethically, providing real value, and satisfying customers. Likewise, there is no legal requirement that waterproofing contractors in Placer County have liability insurance which is critical to reimburse you in the event of any damage that occurs.

Waterproofing is most effective when done at the time of construction because concrete itself is not watertight on its own. One approach is the application of waterproof membranes of various materials like bitumen, silicate, or polymer sheets that act as a barrier between the building and the water. A more recent approach uses additives to the concrete itself, known as integral waterproofing systems. There are two types of integral systems to give concrete a waterproof quality: hydrophilic which replaces the water in the concrete with crystals, and hydrophobic which uses fatty acids to block pores within the concrete, preventing water passage.

But the need for waterproofing contractors in Placer County often involves solving water leaks, water seepage, and flooding in existing structures, especially cellars, basements, and crawl spaces.

Basement Waterproofing
There are two categories of basement flooding. One is surface water entering the basement from the walls, including windows, wall cracks, pipe penetrations leaks, or basement wall seepage. The other category is groundwater in the basement through the floor slab, or the cove joint which is where the basement floor and walls meet. This kind of water seepage is referred to as hydrostatic pressure. Good waterproofing contractors will start by determining if the flooding is through the walls or through the floor (hydrostatic pressure) or both.

Basement Flooding from the Walls
Basement water problems are rarely solved by applying waterproof compounds to the interior walls since those interior coatings will degrade over time or can't handle the pressure of water already penetrating the wall. Cellar dewatering or basement waterproofing is properly done on the exterior, so that water never accumulates around the foundation. This may include grading the soil to keep water at least 15 feet away, installing a drywell if a downhill slope to the foundation is unavoidable, extending gutter downspouts further away from the walls, and correcting window wells that accumulate water.

Basement Flooding from the Floor Slab (Hydrostatic Pressure)
The amount of ground water can increase with rainfall, causing hydrostatic pressure that pushes water through the cellar floor. The most common solution is installing a drainage system which includes a drainage pipe, gravel or drainage stone, concrete to cover the gravel, and a discharge system consisting of a sump basin and sump pump. Proper installation of a basement drainage system will prevent seepage by removing water before it rises to the level of the basement floor and divert it to a sump well recessed in the floor where a sump pump discharges it elsewhere. Basement drainage systems are usually installed along the interior part of the foundation and can be retrofitted into homes when exterior drainage systems fail or don't exist.

Sump pumps ideally should include a battery back-up to prevent failure during power blackouts since storms can be the common source of both rainfall and power outages.
 
Crawl Space Waterproofing
Originally it was believed that moisture control of crawl spaces was achieved by venting the crawl space to the outside. More recent experience indicates that crawl space venting leads to moisture problems like mold, rot and insects because the moisture level of crawl spaces fluctuates with the outside humidity, while a closed crawl space remains dry. For existing crawl spaces, waterproofing a crawl space includes fixing water entry problems, closing off the wall vents, installing a full ground moisture barrier (lining the ground with plastic) inside the crawl space. The crawl space should not be closed off if there is unresolved water entry or if furnaces or water heaters are supplied with air from the crawl space. If the hot water heater relief line and drain pan terminate in the crawl space, piping should be added to run these lines to outdoors to prevent overflow from flooding the crawl space.

Installing a crawl space drain will prevent plumbing leaks and water spills from creating standing water on top of the ground moisture barrier (such as ground lining polyethylene). Moldy crawl space air can be prevented from entering the house by sealing floor holes and duct leaks. Closing the crawl space from outdoors includes sealing wall vent openings with rigid foam and sealing with caulk, expanding foam, or mastic, sealing all wall penetrations for electrical and plumbing, and adjusting the crawl space door or access panel for a tight fit. Sealing a crawl space can reduce moisture levels such that hardwood flooring above it may shrink and show gaps while some previously buckled by moisture have flattened out. Some waterproofing companies may recommend permanently installing a dehumidifier inside the crawl space.

Full Service Waterproofing vs One-Size-Fits-All
Many waterproofing contractors offer only one kind of solution, or their own patented system. If your own research or an independent inspection has already determined that's exactly the kind of waterproofing you need, then it can make sense to hire that company. But if you have not determined yet the exact cause of the problem and the right approach, then a company that sells only one kind of waterproofing might not be the best option.

Some waterproofing contractors are full service, meaning they provide multiple options and approaches and can recommend one based on an inspection of your property and determination of the exact causes of water seepage or water leaks in your case. And remember, cheap waterproofing has not saved you any money when it fails to work, so think long term, and look for written guarantees which can be anywhere from several years, decades or a lifetime warranty.
