Part of the Aggregate Industries business, Lafarge Cement is calling on housebuilders to insist on tighter controls around the use of mortar. This follows claims that the use of substandard product is causing damage to hundreds of new homes.

Following a BBC report that focused on the use of weak mortar, which is seen to be that which does not meet the standards required by the industry. The use of such mortar has led to crumbling being found in properties across 13 estates in the UK. The news has caused widespread concern amongst residents and across the construction industry.

“This latest report is concerning, especially as it has been identified as a potential industry-wide problem affecting hundreds of homes,” said Jeremy Lee, Commercial Director at Lafarge Cement. “As acknowledged by the BBC, mortar performance is a complex issue, with a myriad of factors, including weather and correct specification and application, having a potential detrimental impact.

“However, this is why it is critical that all building products, including mortar, meet required industry standards – which, according to the NHBC, should be one part cement to 5.5 parts sand for most of the UK. But for areas that experience extreme weather conditions, such as Scotland, it is recommended that a higher proportion of cement is used to increase durability.

“Building standards are in place for a reason and tighter controls are needed to ensure that the correct products are specified, as well as being mixed and applied properly onsite. From housebuilders to the wider industry, it is everyone’s responsibility to ensure that adequate and suitable products are used, through a robust specification process and due diligence during all stages of the construction process.”

As part of Aggregate Industries, Lafarge Cement offers a solutions-based packed cement portfolio that is underpinned by robust technical knowledge and the latest production innovation.
