What Are The Different Services Offered By Roofing Professionals Regarding Leakage Protection?

Waterproofing is a long-lasting technique used by individuals and businesses to restrict water ingress in closed structures. Different chemicals, such as liquid and sheet membranes, grouts, and sealants are applied to the surfaces, each with its own characteristics and qualities. Protect your roof with expert roofing professionals. There are two main types of processes for substrate protection:

• Exterior Waterproofing
• Interior Waterproofing

1. Exterior Waterproofing

Exterior waterproofing is applied on the outer side of a structure. In other words, it is an above-grade waterproofing technique. Following is a concise version of the waterproofing process:

• Surface Preparation
• Primer Application (if required)
• Application of Waterproofing Admixtures & Membranes
• Curing Time

Waterproofing Materials

Several materials, such as membranes, insulating materials, and liquid admixtures are applied to walls and other surfaces to prevent roof leaks and water entrainment in basements and other wet areas. Let’s discuss some important materials:

1. Waterproofing Membranes

These coverings are divided into two categories:

• Liquid Membranes
• Sheet Membranes

Liquid membranes are made from different chemicals: Tar, organic compounds, and cement-based additives are some types. These coatings render flexibility, conformity to any surface, seamless application, robust adherence, rapid application, etc.

Sheet membranes, on the other hand, are used for uniformity and smooth application. Its strength and adhesion are better than liquid membranes. Moreover, it is an anti-fracture system together with a waterproofing membrane.

1. Grouts

Grout is a chemical injected into crevices and holes to repair roof leaks, wall seepage, and minor ruptures. It is optimal for masonry, concrete, and other works, such as tiles. It is a mixture that comprises sand, cement, water, and chemicals.

Types of Grouting

• Cement Grouting
• Chemical Grouting
• Structural Grouting
• Resin Grouting

1. Sealants

A waterproofing sealant is a protective coating found in different materials like concrete, masonry, and paint. When applied, it forms a strong barrier on the substrate that prevents rainwater from penetrating. Sealants are optimal for closing down roof leaks, holes, and broken joints. Besides above-grade, the material is also useful for foundation and basement work.

1. Crystalline Admixtures

Also known as permeability-reducing admixtures, crystalline admixtures are used to improve concrete strength or stimulate autogenous fixing of crevices and holes. These chemicals are added to the concrete mix to form insoluble crystals. These crystals fill up the space formed by stress or shrinkage.

Crystalline admixtures offer two types of reactions:

• Immediate
• Delayed

2. Interior Waterproofing

Interior waterproofing relates to re-routing water away from the basement and foundation, installing waterproofing membranes, or covering the inside area with water-resistant chemicals. It is similar to negative-side and blind-side waterproofing in some respects.

During the process, the concrete floor is managed with the wall perimeter. The concrete is removed and the gravel and sand are ploughed out till the base. Tiles are laid around the area with the trench filled with sand and the floor with new concrete.

How to Keep Water Away from Basements? 

• Pipes and drains – To redirect excess water
• Water transferred to a pit
• Sump pump transfers the water to the drainage system
• Vapor barriers installation
• Sealing cracks and leaks

3. Other Systems

French drain is a process in which a perforated pipe and grit-filled trench is installed around the structure, which allows water to be collected and carried away.

Injection waterproofing involves the use of injecting a water-resistant material into crevices and gaps. This ensures a long-lasting seal for homeowners and caretakers.
