Basement Waterproofing

Basement Waterproofing Services for Long-Term Structural Protection

A wet basement is among the main culprits behind building decay in houses, businesses, and industries. As the name implies, basements are set underground, which makes them perpetually subjected to hydrostatic pressures, moisture, and seepage. If left unaddressed, these conditions will allow water to forcefully enter walls, floors, joints, and foundations, resulting in humidity, mold, corrosion, and damage to the structure.

At 20MCC, we offer state-of-the-art basement waterproofing solutions that shield buildings from water penetration for enduring strength. Our specialized waterproofing solutions integrate cutting-edge technology, premium components, and skilled installation methods to guarantee permanent resistance to groundwater and leaks.


What is Basement Waterproofing?

Basement waterproofing is the method of preventing water from entering your basement through walls, floors, joints, and foundation. This involves using specialised waterproofing systems to create a protective barrier against groundwater, seepage, and hydrostatic pressure.

The primary objectives of basement waterproofing are:

  • Prevent water seepage and leakage
  • Protect structural foundations
  • Improve indoor air quality
  • Prevent mold and mildew growth
  • Extend the lifespan of the building

Whether your project involves residential basement waterproofing, an underground parking area, an industrial facility, or a commercial building, our professional basement waterproofing solutions provide peace of mind by protecting your structure from expensive water damage.

Common Causes of Basement Water Leakage

Hydrostatic Pressure

Hydrostatic pressure occurs when groundwater builds up around your foundation. As pressure grows stronger, it presses against your basement walls and pushes moisture through cracks, pores, and other weaknesses in your concrete.

Cracks in Foundation Walls

Over time, due to structural movement, settling, and other environmental factors, cracks may form in your foundation walls. These cracks act as a direct conduit for water entry, which is why foundation waterproofing becomes necessary.

Poor Construction Joints

One of the most frequent places water seeps through is at wall-floor junctions. Faulty sealants in the construction joints may turn out to be weak spots that allow water to penetrate from the ground.

Inadequate Drainage Systems

Poor site drainage can cause water pooling next to your foundation. Moisture around the house increases hydrostatic pressure and thus increases the chances of your basement flooding.

Signs Your Basement Needs Waterproofing

Spotting warning signs early on can prevent significant structural problems and costly repairs.

  • Damp basement walls
  • Water stains on walls and floors
  • White powdery deposits (efflorescence)
  • Mold and mildew growth
  • Persistent musty odors
  • Standing water or puddles
  • Peeling paint and coatings
  • Cracks in walls and flooring
  • Rusting of reinforcement and metal fixtures

If you notice any of these signs, check your basement for leaks right away and get professional help if needed.

Our Basement Waterproofing Solutions

At 20MCC, we provide basement waterproofing services based on your structure's condition, groundwater level, and requirements.


External Basement Waterproofing

External waterproofing, or positive-side waterproofing, protects your structure from the outside before water can reach the concrete.

Our external waterproofing systems include:

Waterproof Membranes

High-performance waterproof membranes provide a continuous barrier to prevent groundwater infiltration and protect below-grade structures.

Protective Coatings

Specialized protective coatings increase longevity while providing lasting protection from moisture, chemicals, and other environmental elements.

Drainage Protection Systems

Drainage boards and protective layers can help divert groundwater away from your foundation, reducing hydrostatic pressure.


Internal Basement Waterproofing

Internal waterproofing (negative-side waterproofing) is often used where excavation on the outside isn’t possible.

Crystalline Waterproofing

Crystalline waterproofing technology penetrates the concrete's pores and reacts with water seeping through it to form insoluble crystals. These crystals fill the voids and capillaries, effectively blocking water pathways and enhancing the structure's resistance to moisture intrusion.

Injection Grouting

Injection grouting is an effective method for sealing active leaks, cracks, and voids in concrete structures. The grout material is injected under pressure to fill gaps and prevent further water penetration.

Internal Waterproof Coatings

Internal waterproof coatings provide an additional protective barrier against water ingress. These coatings help prevent moisture penetration, improve durability, and protect interior surfaces from dampness and water damage.

Foundation Waterproofing

Proper foundation waterproofing is critical for ensuring long-term structural stability.

Our foundation waterproofing systems help:

  • Resist groundwater pressure
  • Prevent foundation deterioration
  • Protect below-ground structures
  • Enhance building longevity

Crack Injection and Basement Leak Repair

Active leaks and structural cracks require immediate attention to prevent further damage.


PU Injection

Polyurethane injection expands upon contact with water, effectively sealing active leaks and stopping water infiltration.

Epoxy Injection

Epoxy injection restores structural integrity by bonding cracked concrete sections together while preventing water penetration.

Joint Sealing

Construction joints and expansion joints are sealed using specialized materials that maintain flexibility and waterproof performance.

Waterproofing Basement Walls – Best Methods

Choosing the right method for waterproofing basement walls depends on the condition of the structure and the severity of water intrusion.

Cementitious Waterproofing

Cement-based waterproofing systems provide durable protection for concrete surfaces and are commonly used in basement applications.

Benefits include:

  • Easy application
  • Strong adhesion
  • Cost-effective protection

Crack Injection and Basement Leak Repair

Active leaks and structural cracks require immediate attention to prevent further damage.

Crystalline Waterproofing Systems

Crystalline waterproofing penetrates deep into the concrete matrix and permanently blocks water pathways.

Advantages include:

  • Integral waterproofing
  • Self-sealing properties
  • Long-term protection
