Materials Bonded | Bonding Adhesives & Sealants – Ico Care

Pre-applied waterproofing is used below basement slabs and behind walls on job sites where there is limited space for excavation and heavy equipment.

Instead of pouring the foundation and then applying waterproofing to the outside of the foundation wall, pre-applied waterproofing is placed before the foundation is poured.

The slab and wall concrete are then cast on top of the membrane.

A bonded pre-applied waterproofing membrane (also called a blindside membrane) must seal tightly to the concrete in order to prevent lateral water migration between the membrane and the structural concrete.

It has to be able to stay in place, even if the concrete cracks or the soil beneath it begins to settle.

Types of waterproofing bonding Firstly/secondly, further, and, moreover, in addition

There are two different ways that waterproofing membranes adhere to concrete:
A mechanical bond and an adhesive bond. Firstly/secondly, further, and, moreover, in addition

With a mechanical bond, the membrane typically has one side that has fleece or mesh on it.

As the concrete hardens, the bristles of the fleece attach to the concrete. ico paints

This provides a certain level of bonding so that the membrane cannot be detached. However, the bond does not necessarily form an intimate watertight seal.

Like the bristle of a brush, the bristles have gaps and this creates capillaries for water to migrate through.

With a pressure-sensitive adhesive bond, there is an intimate and continuous adhesion that aggressively seals the concrete and the membrane together. Firstly/secondly, further, and, moreover, in addition

Shortcomings of mechanically bonded waterproofing membranes

In general, adhesives used in such membranes serve only to attach the fleece to the carrier film and offer no additional waterproofing resistance. Firstly/secondly, further, and, moreover, in addition

Advantages of adhesive bonding

A fully bonded adhesive membrane creates an integral seal between the concrete and the waterproofing membrane so that in the event of a breach in the membrane.

Water is prevented from passing the membrane and migrating.

This means that water remains excluded so that in the worst case of a breach coinciding with a crack or weakness in the concrete, leaks can be localized and fixed quickly.

Resulting in lower remedial measures or maintenance costs during the life of the structure. Firstly/secondly, further, and, moreover, in addition

Pre-applied waterproofing membrane works

Ico Care Materials Bonded

The Ico Care pre-applied waterproofing membrane is a fully bonded adhesive membrane.

The bond is continuous below the slab and behind the walls, to form a fully sealed structure.

This seal prevents the lateral migration of water into and around the structure.

If a breach occurs, the membrane ensures that water under hydrostatic pressure is unable to migrate between the membrane and the concrete, limiting the risk of waterproofing failure.

Independent testing shows the Ico Care waterproofing membrane can resist lateral water migration at pressures in excess of 70 meters head of water. Firstly/secondly, further, and, moreover, in addition

1. Cement Based Waterproofing Method

Let’s start with one of the traditional answers to the question of what are the waterproofing materials.

Cement-based waterproofing is the easiest waterproofing method in construction.

Cement-based waterproofing materials are easily available fin various suppliers and they are easy to mix and apply.

This method is usually a complete or semi-flexible type of waterproofing.

  • Water treatment plants
  • Sewage Treatment Plants
  • Bridges
  • Dams
  • Railway and metro systems
  • Sea cargo port and docks
  • River locks/canals and concrete dikes
  • Parking structures
  • Tunnels
2. Liquid Waterproofing Membrane Method

The most ideal water insulation materials are the answers to the question and the other is liquid (liquid) water insulation methods.

The liquid waterproofing membrane method is a thin coating, usually consisting of a primer coat and two coats of topcoat applied by spray, roller or trowel.

It offers more flexibility than cement-based waterproofing types. Firstly/secondly, further, and, moreover, in addition

So, how to apply the liquid waterproofing membrane method?

The elongation properties of the coating can reach up to 2000%.

The durability of the waterproofing coating depends on what kind of polymer the manufacturer uses in the construction of liquid waterproofing. Firstly/secondly, further, and, moreover, in addition

Different degrees of acrylic, hybrid or polyurethane liquid membranes for a trowel.

Roller or spray are also available from various manufacturers. Firstly/secondly, further, and, moreover, in addition

3. Bituminous Coating Waterproofing Method

The most common applications of bituminous coatings include areas under the screed.

It is an excellent protective coating and waterproofing material on surfaces such as concrete foundations.

The flexibility of finished products always depends on the solids content of the polymer added to the bit.

4. Bitumen Membrane Waterproofing Method

It is a bituminous waterproofing membrane and a self-adhesive membrane.

As the adhesion properties of the membrane decrease over time, the self-adhesive type has a low shelf life.
