Protectodrain

Description

A tough, puncture resistant, flexible, UV resistant, moulded polyolefin sheeting material.

Its unique cuspated design gives increased drainage ability as well as high strength, impact and damage resistance.

Uses

Chemind Protectodrain is specially designed for the protection of all Chemind tanking membrane systems, as well as for Grace Bituthene^® self-adhesive sheet and Procor^® membranes.

It provides excellent low cost protection and uninterrupted drainage to basement walls, lift pit walls, retaining walls and planter box walls, as well as floors and landscaped podium decks.

Features

Economical material and installed costs.

Light weight, easy to transport & handle.

Does not apply a shear load to vertical membrane surfaces.

Simple adhesive or tape fixing – no props or membrane damaging nails & pins are required.

Does not absorb water or rot.

Facilitates drainage to outlet drains.

Conforms readily to most irregular surfaces, curved walls, columns etc.

Suited to horizontal & vertical surfaces.

Contains no bitumen, asbestos or phenol.

Non-toxic to plant root systems.

Preparation

Installed waterproofing membranes must be carefully inspected to insure that there are no signs of damage. Repair damaged areas before Chemind Protectodrain placement proceeds.

Application

To the clean membrane surface, install Chemind Protectodrain sheets. Cut, score, bend fit or otherwise apply to the membrane surface.

Hold in place with adhesive compound, waterproof adhesive tape or use Grace Bitustik™ Tape adhesive strip.

Butt join sheets to give a neat finish.

Use Chemind Rendaflash PVC cover strip as a top edge detail, fixed at approximately 300-500 mm centres. Refer any unusual or specific application requirements to Chemind Construction Products Technical Dept.

Protectodrain is used with Chemind Rapid-Drain to protect and facilitate drainage of all tanking.

Do not use pins or other mechanical fasteners that may penetrate or damage the waterproof membrane.

Coverage

Each sheet of Protectodrain will cover approx. 2.16 m². Allow 5% wastage for cutting and loss.

Each roll of Protectodrain will cover approximately 60 m². Allow 5% wastage for cutting and loss.

Packaging

Chemind Protectodrain sizes are:

1.8 m x 1.2 m sheets and

1.2 m x 50 m (60 m²) rolls

Storage

As Protectodrain is very lightweight, it should be stored in a protected area or weighted to prevent displacement by high wind. It is otherwise unaffected by short or medium term exposure to the elements.

Shelf Life

Fully protected sheets and rolls of Protectodrain that are protected from surface contamination, will have an indefinite shelf life.
