Damp Proofing & Plinth Beam/Wall Waterproofing Using HDPE Sheets

by AWEI – Ankit Waterproofing Engineers Inc.

At AWEI, we offer robust damp proofing and plinth-level waterproofing solutions using high-quality HDPE (High-Density Polyethylene) membranes — engineered to block moisture ingress and protect structures from rising damp and long-term deterioration.

🧱 Areas We Protect:

* Plinth beams

* Foundation walls

* External walls in contact with soil

* Damp-prone ground floor slabs

🔍 Why HDPE Membranes?

HDPE sheets are highly durable, impermeable, and resistant to chemicals, roots, and soil pressure. When applied correctly, they act as a continuous barrier that prevents groundwater or capillary rise from penetrating the building envelope.

🛠️ System Application:

* Surface Cleaning & Leveling

* Priming (if required)

* Laying of HDPE Membrane (loose-laid, torch-bonded, or adhesive-backed depending on site conditions)

* Overlap Welding or Sealing of joints

* Protection Board or Screed Overlay before backfilling or surface finishing

✅ Key Benefits:

* 100% waterproof barrier

* Excellent tensile strength and puncture resistance

* Resistant to chemicals, fungus, and soil reactions

* Long service life, even under harsh site conditions

* Compatible with damp-proof courses and vertical wall protection

🌐 Typical Use Cases:

* Residential and commercial foundations

* Basement-to-plinth transitions

* External walls exposed to soil or landscaping

* Industrial setups requiring deep foundations

AWEI’s HDPE sheet system ensures dry, damage-free structures from the ground up — 

a foundation built to last.
