<strong>When</strong> to consider UHP <strong>water</strong> Jetting over abrasive grit blasting


<strong>When</strong> and why should<br />

you use UHP Water<br />

Jetting over Abrasive<br />

Blasting?<br />

UHP <strong>water</strong> jetting safely removes tough, hazar<strong>do</strong>us,<br />

or contaminated materials from any surface.<br />

UHP Water jetting (Ultra High Pressure) – works through concentrated<br />

high-pressure <strong>water</strong> that <strong>will</strong> remove material, coating or contamination<br />

from any surface in the safest and most efficient way possible.<br />

The power of UHP <strong>water</strong> cuts straight through the coating and<br />

hydraulically peels it away from the substrate, where as abrasive grit<br />

blasting has to wear the surface <strong>do</strong>wn<br />

<strong>When</strong> stripping abrasion resistant or pliable materials such as rubber, GRP, polyurea hotspray coatings etc the benefits of UHP over abrasive grit<br />

blasting becomes more pronounced. Likewise the thicker the material the more advantageous <strong>water</strong> jetting is as it <strong>do</strong>esn’t rely on wearing the<br />

surface <strong>do</strong>wn but strips the material away just like removing wall paper.<br />

Not <strong>only</strong> <strong>will</strong> it get the job <strong>do</strong>ne faster and using <strong>only</strong> <strong>water</strong>, you <strong>will</strong> not <strong>only</strong> save money on the abrasive git but you <strong>will</strong> have far less to clean up...<br />

Once the coating or rust has been removed <strong>water</strong><br />

jetting can be used to give the required surface<br />

finish.<br />

UHP Surface Preparation Means:<br />

• No landfill waste is created other than<br />

the removed product.<br />

• Access scaffolding and debris<br />

protection can be avoided by using our<br />

“Limpet Crawler” System<br />

• No abrasive blast media used, which<br />

means there is no respirable dust<br />

created.<br />

• If the situation requires the <strong>water</strong> can<br />

be recovered, treated and disposed<br />

of in a safe, environmentally friendly<br />

manner.<br />

RGL have been selected to carry out the concrete surface preparation<br />

on an 18 storey tower block.<br />

The main contractors for a major revitalisation project faced several challenges<br />

when faced with the first phase of the refurbishment.<br />

How to:<br />

• remove the Polyurea hot spray coating that had been applied to the tower<br />

block back in the 1980’s.<br />

• ensure the substrate was not damaged during the removal process.<br />

• avoid damaging win<strong>do</strong>ws and other external fittings as the surface is removed.<br />

• minimise disruption to the residents through waste materials management.<br />

The polyurea technology stems from the Polyurethane family. It is known particularly<br />

for its abrasion resistance, excellent adhesion and ability to fight corrosives, strong<br />

durable finish, <strong>water</strong>proofing capabilities.<br />

These properties along with the need to minimise waste product meant the<br />

abrasive grit blasting had to be discounted.<br />

Chemical solutions were available but again these had several drawbacks such as<br />

heat required to soften the paint, application and cure time. Chemical removal was<br />

also discounted.<br />

The solution was UHP <strong>water</strong> jet removal. Using <strong>water</strong> pressure of 2800bar RGL<br />

services could systematically peel off the paint whilst leaving the concrete substrate<br />

and expansion joints in tact.<br />

As there were no abrasives or chemicals used the <strong>water</strong> could be safely allowed<br />

to enter the storm drain systems on the ground below. That meant that the waste<br />

materially could be easily contained, collected and disposed of with minimal<br />

disturbance and disruption to the residents.<br />
