Question 1

What is a foundation drain?

Accepted Answer

A foundation drain (often called a French drain) is a system installed around the foundations of a building. It captures and evacuates accumulated water in the soil to reduce hydrostatic pressure on the foundation walls.

Question 2

When should a foundation drain be redone?

Accepted Answer

It is recommended to check or replace a foundation drain if your house is over 25-30 years old, if you observe water infiltration or humidity odors, if cracks appear on the foundation walls, if the existing drain is made of terracotta or concrete, or if the system does not comply with current standards.

Question 3

What are the services offered for foundation drainage?

Accepted Answer

TEREXCA offers inspection of existing drains, targeted excavation, installation or repair of French drains, installation of access manholes, cleaning and unblocking of drains, waterproofing of foundations, and backfilling and restoration of the land.

Question 4

Why is it important to repair a foundation crack quickly?

Accepted Answer

Even a seemingly minor crack can lead to water infiltration, humidity, mold, deterioration of concrete and foundation walls, and damage to interior finishes. Quick intervention prevents more costly repairs and preserves property value.

Question 5

What is the repair process for foundation cracks?

Accepted Answer
