GNBS urges manufacturers to use its concrete block testing service

-as consumer complaints pour in

The Guyana National Bureau of Standards (GNBS) is advising manufacturers and contractors to utilise its concrete hollow block testing service as it receives numerous complaints from consumers about the quality of blocks being offered for sale.

Public Relations Officer of the GNBS, Mr. Lloyd David

Public Relations Officer, Mr. Lloyd David says the GNBS is now fully capable of testing the compressive strength of locally manufactured concrete hollow blocks.

“We believe that concrete block makers need to understand the strength of the blocks they are making, which ultimately will benefit the consumers because they will not have to buy blocks that are defective and weak in strength.

Sometimes, when you buy the blocks, they are weak, all fall apart in their hands. The GNBS has been receiving a number of complaints regarding this and we believe that it is important that we offer such a service,”Mr. David said.

A laboratory technician from the Industrial Metrology and Testing Department measures a concrete block.

As such, the GNBS is encouraging local manufacturers, domestic block makers, contractors, and homeowners, who have long called for this service, to submit samples to its laboratory for initial or routine testing.

“The process is simple. If a block maker comes to the GNBS and we recognise that the blocks are not meeting the requirements, the moisture content and so is not adequate, we will offer guidance to those manufacturers.  

What we are advocating now is for manufacturers to come and get their blocks tested so that they can understand the requirements. By understanding that and not reaching the requisite pounds per square inch (PSI), you will need to strengthen the blocks and make them better,” Mr. David said.

Hollow blocks of common sizes including three inches, four inches and six inches can be tested.

Mr. David said the GNBS is also now able to certify blocks tested under its certification programme.

Manufacturers and even smaller suppliers can submit one to five blocks for quality testing, and 10 blocks for certification.

In addition to concrete blocks, the GNBS has a range of standards for building materials such as nails and zinc.  The Bureau is working to improve testing facilities for all building materials to ensure consumers benefit from quality products.
