Basement Waterproofing – Different Types of Waterproofing

Basement Waterproofing – Different Types of Waterproofing

Exposure and stress from the prevailing permanent or temporary environmental conditions can result from fully or partially exposed basement. The construction method and sequence, ease of application, and total cost management are some of the requirements faced by the basement. In addition, sustainable system solutions are becoming more important in order to save natural resources, energy and water, plus reduction of CO 2 This leads to expensive structural repair works, damage or loss of interior finishes and goods, operational downtime, or serious impact on the environment.

Type of Exposure and Stress in Basement ;

  • There are different levels of exposure and pressure.
  • Sulfates and chlorides are in solution.
  • The static forces are not equal.
  • Dynamic forces (e.g. from settlement, earthquake, explosion, etc.)
  • The temperature can change during the day and the night.
  • Gases in the ground (e.g. Methane and Radon)
  • Plants have aggressive biological influences.

Signs of basement water damage in basement

  • Cracks can be horizontal, vertical, diagonal or stairstepped. Structural damage can be seen by widening cracks.
  • Buckling walls can be caused by pressure. Walls seem to be bowed.
  • Peeling paint is caused by water leaking through walls.
  • There is a white powdery substance on the basement walls.
  • After exposure to mold, it can cause respiratory problems.

The selection of the appropriate method, the project specific design of the chosen system, and the correct installation on site are some of the key elements that can be used to reduce future maintenance and repair costs. Water can enter the basement of a structure using techniques and materials. A basement that is below ground level can require the application of sealant materials. The space of the basement is prone to wetness. Water in the soil can cause pressure to be exerted on the walls and floors. Major structural damage as well as mould, decay, and other problems can be caused by this pressure.

Types of basement waterproofing methods

Exterior basement waterproofing

The exterior basement waterproofing method is designed to prevent water from causing any major structural damage to the building.

Interior basement waterproofing

The main source of wetness is condensation. It works if the problem is small. One of the best ways to save your basement is by installing a backwater valve. A drainage system is the most complex solution.

Interior basement waterproofing

Integral basement waterproofing

The concrete structure has a waterproof system in it. The structure itself stops liquid water from entering the basement. Joint seal systems are used for connection, construction and movement joints.

Different types of materials used for basement waterproofing

To temporarily block the passage of water through a crack or void, a foam is designed. They form a tough and elastic foam when they react with water.

The non-structural injection seal and waterproof of voids, cracks and joints can be done with the use of the Polyurethane. Good penetration into the concrete structure can be achieved with their low viscosity.

Structural repairs can be made by injecting cracks and voids in load bearing reinforced concrete structures. Their low viscosity allows penetration into cracks in the structure and this also helps to ensure permanent anddurable load transfer based on their excellent adhesion to the concrete.

Flexibility in adaptation of the injection material to the prevailing conditions on site is possible because of their reaction time being adjusted.

Microfine cement suspension is based on blends of microfine cements.

Different types of basement waterproofing membrane products

Depending on the needs and requirements each of the different types of basement waterproofing products is used Below is a list of them.

Strong bonding strength is provided by the 1.5mm thickness concrete leveling of theModified Bitumen Membrane. It has good properties.

A flexible, non-Reinforced, Polyvinyl Chloride Membrane has a thickness of 2mm It’s made of Polyvinyl Chloride and has a dual-tone hue.

A fully Bonded HDPE Membrane has a 1.2mm thickness and is poured against it to prevent water migration.

Synthetic EPDM rubber is used for the single-ply rubber.

Under 100m head in water retaining and below ground structures, the Portland cement-based membrane can help in resisting positive and negative pressure.

The active chemicals combine with the free lime and the capillary tract to form insoluble complexes.

There is a compound system consisting of a Bitumen Emulsion with Additives and a Powder component.

The cell mesh that bonds with the concrete is a seal. This keeps water out. It can be installed quickly with no need for primer, protection or blinding.

EPDM membrane waterproofing

It is suitable for waterproofing buildings inside and outside as well as foundation skirting. Even in bad weather, it cures quickly. It is a thick film.

It has high strength and puncture resistance and can survive structural stresses.

It has good flexibility and has superior low-temperature application. The top surface is a tough and durable one. Silicone coated release film is used for the self-adhesive side.

This type of membrane is used to mask the surface. Quality control for thickness is possible, and they are suitable for deep and large basements.

There is a single-ply rubber waterproofer being used. It is the best material for waterproofing a high water table.

The type of basement construction, depth below ground, and the proposed end use are a few of the factors that will affect the choice of waterproof system. Major problems can be caused by water damage. There are a lot of factors that come into play when it comes to basement safety. Professional advice on issues that need to be addressed should be given by someone who is knowledgeable. It is advisable to select a basement contractor.
