Membrane Waterproofing for Stair Cores & Basement Steps

by

The Importance of Waterproofing Your Steps:

Without any waterproofing protection, environmental factors can quickly shorten the lifespan of your steps. Water seepage and ingress can cause significant damage, compromising the integrity of the structure and leading to issues like rotting, cracking, or corrosion.

As with all external waterproofing, environmental conditions play a major role in the longevity of the waterproofing system. Without proper care or application, water seepage and ingress can take a toll, compromising your steps’ integrity.

Reasons Why Your Steps Might Be Compromised:

  1. Improper drainage: If there’s not enough drainage to channel water away from the steps, it can quickly lead to leaks in the surrounding walls.
  2. Environmental factors: Heavy rainfall can lead to water leaking into your basement or surrounding walls, especially around exterior stair cores.
  3. Aging materials: Over the years, wear and tear, combined with seasonal weather changes, can break down waterproofing layers and materials.

Why Waterproofing Matters:

  • Durability: It extends the life of your steps, preventing costly repairs and deterioration.
  • Protection: Waterproofing keeps water out of your walls and foundation, protecting your entire structure.
  • Prevention: It helps minimise potential issues during storm seasons, particularly when there’s significant rainfall.

Methods for Water Proofing Stair Cores:

We offer two primary methods for waterproofing stair cores:

  1. Membrane Application
  2. SNSeal Injectable Sealant & Membrane Application

In some cases, a combination of SNSeal Injectable Sealant and Membrane Application may be necessary, especially in areas with significant water ingress issues. Below, we outline the steps taken to address water ingress using both methods.

First Approach: Membrane application:

External Steps, angle from bottom of steps upwards. Stair Core with Water Ingress Issues - leaking into adjacent walls. Can see watermark stains on steps

1️⃣ Identify Water Ingress on Stair Cores

2️⃣ Preparation for Primer & Membrane application

3️⃣ Application of Primer on Stair Cores

External Steps, angle from bottom of steps upwards. Stair Core with Water Ingress Issues Addressed no longer leaking into adjacent walls. Can see light membrane running along on edge of steps

4️⃣ Stair Cores Membraned

Second Approach: SNSeal Injectable Sealant & Membrane application:

Water Ingress evident on steps - water mark stain and moulding

1️⃣ Pinpoint Gaps:

Meticulously identifying potential problem areas is crucial for effective sealing.

2️⃣ Precise Drilling:

For targeted application of SNSeal, precision is key—this ensures we apply the sealant exactly where it’s needed most.

3️⃣ Injection of SNSeal Injectable Sealant:

Under high pressure, this powerful application guarantees a tight seal to keep water out.

4️⃣ Protective Membrane Applied:

Our final step provides a strong defense against the elements for long-lasting protection.
