Maintaining proper drainage, especially around the perimeter of your foundation, is one of the simplest yet most cost-effective ways of preventing foundation damage. Prioritize installing proper drainage systems in your property. Poor drainage, if not resolved early, could lead to structural damage, which is much more expensive and complicated to repair.
Request a drainage inspection.
The following are typical indicators of water intrusion:
You'll find this on concrete or block walls.
This white, chalky substance is in itself harmless, but because it indicates the presence of excessive moisture, you should not take it lightly. Water intrusion, in the long run, may eventually cause your home's concrete or block walls to crumble.
Due to poor drainage resulting in the presence of excessive moisture, the soil around your foundation can become heavier. This increases the pressure exerted by the soil on your foundation walls and this, in turn, can cause your foundation walls to bulge, lean or crack.
The moisture trapped in the soil around your foundation, if not drained off properly, can freeze and turn to ice crystals during winter. These ice crystals exert additional pressure on your foundation and its members. Your foundation walls can bulge, lean or crack in result.
Excess moisture in the soil around your foundation can cause the soil to sink, therefore causing your foundation to settle. Foundation settlement, in turn, causes cracks in the walls of your foundation, sloping floors and doors/windows that stick or are misaligned.
One or more of the following may be installed to improve drainage and prevent long-term foundation damage:.
A sump pump is installed to pump water out of the basement, crawlspaces and other areas where long-term water pooling can cause the most structural damage. This may be the homeowner's first line of defense against water accumulation around the foundation.
Sump pumps come in two basic types: upright (also commonly called the pedestal sump pump) and submersible.
Upright pump: The upright model's motor is on top while the pump mechanism is found at the base, which sits at the bottom of the sump. A ball float turns the pump on and off. In this type of pump, the motor should not get wet.
Submersible pump: The submersible sump pump model is designed to be entirely submersible and sit at the bottom of the sump. The on/off switch can be either a ball float connected to an internal pressure switch or a sealed, adjustable, mercury-activated float switch. The sealed, mercury switch is generally more reliable than the pressure switch.
Things to check on your sump pump:
Grading is the process of contouring the ground (i.e. making sure it's sufficiently sloped) to ensure that water is channeled away from the building, particularly from the building's foundation.
To ensure that water will not pool around the foundation, drainage devices like gutters, downspouts, catch basins, area drains, and/or trench drains may have to be installed.
Gutters and downspouts that empty water onto or very near the foundation have to be corrected or repositioned so they can take water farther away from the foundation.
French drains attract, collect and divert underground water away from areas which could be damaged by water accumulation and excessive moisture. They are usually built around the exterior wall of the foundation. French drains are also used behind retaining walls to relieve ground water pressure.
The following are the typical steps of French Drain construction:

"Sinai Construction redefines professionalism in the Los Angeles construction business! Of all the construction companies I've called to evaluate the repairs needed for our home's foundation, only Sinai Construction took the time to inspect the actual foundations, take pictures, make a detailed report and explain to me not just the repairs needed to be done but what caused the damage in the first place."
