Deck Membrane Repair: Complete Waterproofing Guide

Deck Membrane Repair: Complete Waterproofing Guide

Looking for deck restoration near me? Did you know that polyurethane membrane waterproofing involves applying a liquid polyurethane coating to the roof or surface to be protected from water leaks? Yes, the ideal choices of deck membrane repair. 

When is a deck membrane repair necessary? 

You don't have to wait until water starts leaking to take action. There are clear signs that a roof needs attention: 

·        Leaks and drips: If you notice damp patches on the roof or walls, this is an indication of problems with the roof.

·        Shifted or broken tiles: A quick look at tiled roofs can reveal parts in poor condition.

·        Wear and tear on the waterproofing membrane: If the water proofing membrane is damaged, water can easily seep in.

·        Thermal insulation problems: If the building loses heat in winter or accumulates too much heat in summer, it may be due to deficiencies in the roof.

·        Material detachment: If you find fragments of the roof on the ground, it is a sign that something is wrong. 

Deck membrane repair options

Depending on the type of roof and the problem identified, there are several solutions: 

Waterproofing

When the primary issue is water infiltration, applying a new waterproofing layer is one of the most effective solutions. Materials such as asphalt membranes, liquid polyurethane systems, or EPDM can be used, depending on the specific roof type.

If the roof is severely deteriorated, it may be necessary to renew it completely. This is common in older buildings or when partial repairs are not sufficient. In this case, it is used to improve the building's thermal insulation and energy efficiency. 

Inclement weather and air pollution can cause wear and tear on roofs.

If proper treatment is not applied, moisture will eventually seep into buildings, causing significant damage to the structure and quality of life. 

The polyurethane membrane waterproofing deck membrane repair system is the ideal method to prevent and solve this problem, both due to its effectiveness and its value for money.

When the membrane is applied, it polymerizes, creating a coating of excellent strength and elasticity. A permanent polyurethane layer is created, perfectly bonded to the substrate and free of any joints or overlaps that could compromise the roof's waterproofing. 

It is especially effective on:

  • Terraces and exposed roofs are intended for frequent pedestrian and vehicle traffic.
  • Terraces and roofs with a backing.
  • Pitched roofs or flat roofs. 

If the roof or terrace will only be subject to occasional pedestrian traffic, you can also opt for waterproofing with acrylic membranes.

Furthermore, its easy liquid application allows it to adapt to all types of roofs—even those with irregularities, corners, and breaks—such as:

  • Paving.
  • Tile or slate roofs.
  • Industrial roofs with sprayed polyurethane.
  • Gutters or viaducts.
  • Planters. 

What are the advantages and properties of deck membrane repair with a polyurethane membrane? 

Polyurethane Elastic Membrane is a single-component, 100%water-based, aliphatic elastic membrane. Once applied, cured, and dried, it forms a seamless, breathable, and highly weather-resistant hydrophobic film that is fully adhered to the substrate. It is highly weather-resistant and eliminates water infiltration problems. It acts as an "anti-fracture membrane." It offers excellent elongation capacity throughout its use fullife. 

  • It provides greater resistance to water stagnation in deck membrane repair than an acrylic system.
  • 100% waterproof hydrophobic membrane. Resistant to water ponding, it can be used on flat roofs.
  • High stability outdoors and against atmospheric agents (rainwater, frost, high sunlight). High frost resistance.
  • 100% aliphatic polyurethane, non-yellowing. High UV resistance. 

Easy to apply with a brush, roller, or airless spray 

 It does not require specialized personnel or a hot application. It outperforms other traditional systems and eliminates the risk of using a blowtorch. 

  • Easy to clean and maintain. If damaged, the membrane can be repaired.
  • High resistance to immersion in water and frequent water contact. Maintains water tightness at two points where rainwater tends to accumulate frequently.
  • Forms a continuous coating, without overlaps or joints, with high tensile strength. Adaptable to structures with irregular geometry.
  • Fast-drying, allowing repainting within 24 hours.
  • High mechanical resistance to pedestrian and light vehicle traffic.
  • Contains an anti-mold preservative.
  • Good hiding power.
  • Water-based product: low odor and environmentally friendly.
  • Once opened, it can be resealed for subsequent use.
