Complete Basement Waterproofing

In recent years, Australasia has seen a dramatic rise in the construction of multi-storey commercial buildings, particularly mixed-use and residential tower developments. One factor common in most of these is a basement structure used for car parking, storage and utility areas.

These basements need long term waterproofing solutions. It is not commercially viable, and often not even possible, to fix or upgrade failed basement waterproofing systems. Any solution must be able to last the expected design life of the building and more.

Leave a legacy for the longevity of the structure!

Moisture, Steel Corrosion, and Structural Integrity

Not only is it crucial to keep the usable space dry, it is also imperative to maintain the integrity of the structure itself. Moisture is the biggest factor in the corrosion of reinforcing steel.

As you may know, water can seep through perfectly intact concrete, given enough backpressure (e.g. forced by gravity). To achieve a dry result, you need to waterproof the concrete itself. This provides a barrier against seepage which is not dependent on the durability of membranes or tanking.

A thorough concrete waterproofing solution

For a thorough concrete waterproofing solution, Markham Global offers the complete, guaranteed BASE-TECT waterproofing system, giving long-term peace of mind. This includes an assessment of your project, including factors such as concrete design, site conditions and water table.

Design recommendations, documentation and detailing are provided, along with meeting key stakeholders to address all concerns. “The devil is in the detail” with basement waterproofing, and you need to be sure of a thorough, complete result. Markham will then provide on-site support, with approved applicators, supervision and a strict quality assurance process.

Essentially the system includes:

• AQURON 300 or CONQOR B50 hydrogel waterproofing admixture in the concrete mix
• AQURON 2000 penetrating hydrogel for curing and secondary waterproofing
• Joints are sealed with CONQOR 47B or 87B hydrophylic gaskets and polyurethane sealants.

The BASE-TECT waterproofing system is proven for over 20 years, giving a long-term high-quality waterproofing result. You will find this system provides excellent value for money. Due to the limited detailing of junctions, it allows fast on-site installation.
