Metflex in the Water Industry

Eliminating water contamination

Project: Craigie reservoir roof
Client: North of Scotland Water Authority.

Problem

The Reservoir roof was allowing water and residues from animal droppings through into the underground reservoir, thus contaminating the water.

Solution

Spray-apply Metflex multi-purpose, elastomeric coating to a thickness of 1.5 mm totally waterproofing the roof. An environmentally friendly grass green colour was chosen to merge the reservoir into the surrounding landscape

Result

An instant hard wearing, water proof, oil resistant, impermeable coating that is aesthetically pleasing to the surrounding environment and enabled return to service immediately after spraying.

The full treatment for the works

Project: Primary and dosing chamber tanks, Sewage Treatment Works, 
Slingsby, North Yorkshire.
Client: Northumbrian Water Ltd.

Problem

Primary and dosing chamber tanks of a brick construction had deteriorated with age causing major leaking

Solution

Grit blast all surfaces, to clean and prepare substrate. Repair missing / defective render with Tapecrete cementitious mortar. Spray-apply Metflex multi purpose, elastomeric coating to a thickness of 1.5 mm in a selected brown colour .

Result

A durable waterproof lining which completely resolved the leakage problem.

Treated in less than 8 hours

Project: Sewage treatment tank, Little Kildale, North Yorkshire.
Client: Northumbrian Water Ltd.

Problem

Brick constructed sewage treatment tank was showing signs of deterioration through age and was leaking. Most joints were missing and large holes were evident.

Solution

Clean the inner surface of the tank by power wash. Mechanically fix geotextile to the inner surfaces of the tank. Spray-apply Metflex elastomeric coating to a nominal thickness of 1.5 mm.

Result

An instant waterproof lining solving the leakage problem. Duration of works and return to service within 8 Hours.

Short downtime for long canal

Project: Brecon - Monmouth Canal, Abergervenny.
Client: British Waterways.

Problem

Deterioration and spalling of existing concrete surface on the canal floor and walls had led to significant water loss from the canal. The Welsh Water Authority wanted to minimise closure time for each section of canal and also implement a long term solution with minimum maintenance.

Solution

Spray apply Metflex elastomeric membrane to nominally 1.5 mm thickness to provide an abrasion-resistant, hard-wearing, low maintenance, flexible waterproof lining to the canal.

Result

Fully waterproof lining to canal sections which were able to be re-opened immediately after spraying had finished.

Preventative application of a proven approach

Project: Ugthorpe reservoir roof.
Client: Yorkshire Water Plc.

Problem

Similar structures had suffered from problems of water contamination due to water and residues from animal droppings seeping through into underground reservoirs. This newly constructed reservoir roof was thus deemed to require a proven preventative treatment to eliminate the potential for such problems.

Solution

The reservoir roof was sprayed with Metflex elastomeric coating to a thickness of 1.5 mm to seal and totally waterproofing the roof.

Result

An instant, hard-wearing, waterproof, oil-resistant, and impervious membrane that was returned to service immediately after spraying. Surface finishing to meet environmental requirements involved a dolomite overlay prior to back-filling with soil.
