Professional Waterproofing Services

Long-Term Protection Against Water Damage, Dampness & Structural Deterioration

Water intrusion is one of the most destructive forces affecting buildings. At Slon Construction & Projects, our waterproofing services are designed to prevent moisture penetration at its source—protecting structural integrity, interior finishes, and long-term property value. We deliver specialised waterproofing solutions for residential, commercial, and industrial structures using proven systems and professional application methods.

Water Damage Is Progressive, Prevention Is the Only Solution.

Unchecked moisture infiltration leads to structural weakening, mould growth, paint failure, electrical hazards, and escalating repair costs. Waterproofing is not merely a repair service; it is a preventive construction system that must be correctly designed, applied, and maintained. Our approach focuses on identifying vulnerability points and sealing them with durable, environment-appropriate waterproofing systems.

Waterproofing Done Right the First Time

Technical Assessment. Correct System Selection. Professional Application.

The Best Waterproofing Services

  • System-Based Waterproofing  - We do not rely on one-size-fits-all products. Each project receives a waterproofing system selected according to exposure, surface type, and structural movement.
  • Root-Cause Diagnosis - We identify the true source of water ingress, whether surface failure, structural cracks, or drainage issues, before application begins.
  • Long-Term Performance Focus - Our waterproofing solutions are designed for durability, flexibility, and resistance to weather cycles, UV exposure, and standing water.

Failed waterproofing is almost always the result of poor diagnosis or incorrect material use. We eliminate guesswork by applying industry knowledge, site-specific evaluation, and proven waterproofing methodologies.

Protection for Flat Roofs, Pitched Roofs & Roof Penetrations

Roof Waterproofing Services

Roof waterproofing addresses leaks, ponding water, cracked membranes, and failed joints. Our systems protect roofing structures against rain, heat expansion, and long-term weather exposure.

Balcony & Terrace Waterproofing

Preventing Water Penetration in Exposed Living SpacesBalconies and terraces are high-risk moisture zones due to direct exposure and foot traffic. Our waterproofing systems prevent water migration into slabs and internal ceilings below.

Bathroom & Wet Area Waterproofing

Critical Moisture Control Behind Tiles & Fixtures
Bathrooms and wet areas require concealed waterproofing beneath finishes. We install compliant systems that prevent leaks, mould growth, and tile failure.

Foundation & Structural Waterproofing

Defending Buildings from Rising Damp & Ground Moisture
Foundation waterproofing protects against ground moisture intrusion, rising damp, and long-term structural degradation. Ideal for basements, retaining walls, and ground-level structures.

Waterproofing Repairs & Maintenance

Correcting Failed Systems & Extending Waterproofing Life
Cracked membranes, peeling coatings, and recurring leaks signal system failure. Our repair services restore waterproofing integrity and extend service life without unnecessary demolition.

Waterproofing Systems & Materials Guide

Understanding Membranes, Coatings & Application Methods
This guide explains the different waterproofing systems, including liquid membranes, torch-on membranes, cementitious coatings, and elastomeric systems, helping clients make informed decisions.
