Waterproofing Accounts for 83% of Building Complaints

There is a statistic often quoted in the building industry. Waterproofing is 1.8% of construction cost but accounts for 83% of building defect complaints.

Engineered Waterproofing

Selecting the correct membrane is crucial. We work with industry suppliers to ensure: rigorous profile (terminating) design (a significant point of failure); appropriate elongation properties to allow for building movement and expansion joints, UV stable when required, acid resistant where this is important; and a welding mechanism that will last. We work to ensure long term solutions that we warrant. We work with polymeric membranes where appropriate, where more brittle monomeric membranes might fail. We partner with suppliers who are committed to continue developing products to meet the Australian environment.

Quality Solutions

Quality solutions require correct diagnosis of the problem, selection of appropriate quality product and installation by skilled applicators.

Andersal has successfully repaired a wide variety of waterproofing problems in almost every type of structure in Sydney.

The most common causes of waterproofing failure are:

Membrane reaches the end of its effective service life.

Building Movement

* Building settlement, building movement or expansion joints having caused the membrane to tear or rip loose from edges or flooring.
* This may be exacerbated by selection of an inappropriate membrane, e.g. one with inadequate elongation properties.

Lack of Contractor Expertise

There is an acknowledged shortage of skilled contractors in the industry.

Correct Diagnosis

Failure of the previous maintenance or repair is often caused by incorrect diagnosis. In particular, failure to fix the root cause of the problem is due to inadequate understanding of the issue, inappropriate product selection, lack of installation expertise or cost cutting in order to obtain the job.

Cost Cutting

Contractors may cut costs by omitting recommended primers or selecting inferior and inadequate products. There are many installation techniques that are important to the performance of the waterproofing system.

It is imperative to select a competent contractor, as waterproofing failure often results in asset damage and capital value depreciation out of all proportion to repair cost.

Andersal Engineering Concrete Repair | Andersal Engineering

Skilled contractors can effect a complete restoration of integrity by removal of damaged concrete, treating or replacing and retying reinforcement and applying a suitably designed concrete mix. This results in inadequate cover around the reinforcement which causes the concrete to crack leading to water ingress, subsequent exposure and contamination with chlorides.
