DL E&C is accelerating innovation in bathroom construction quality and productivity with its newly certified dry wall waterproofing system.
On May 13, DL E&C announced that its 'Dry Wall Waterproofing System for Bathrooms,' developed in collaboration with Hansol Home Deco, has received certification from the Ministry of Land, Infrastructure and Transport. This certification is awarded to new or improved technologies that demonstrate novelty, advancement, and applicability in the field.
The new technology has been highly praised for addressing the limitations of traditional wet construction methods. Typically, bathroom construction involves stacking bricks with cement and then attaching tiles, a process that requires additional waterproofing and curing, resulting in longer construction times and the need for skilled labor.
In contrast, DL E&C's dry construction method utilizes 16 large waterproof panels (2440×590mm) for a lightweight wall in a bathroom measuring approximately 16.3 square meters. This approach eliminates the need for a curing process, thereby shortening construction time and enhancing efficiency.
Notably, this technology is similar to the box-type modular construction methods that are gaining traction in the industry. Bathrooms, traditionally seen as wet spaces requiring waterproofing and tiling, can now benefit from standardized construction and simplified processes through the introduction of the dry system. DL E&C has previously secured foundational technologies related to box-type modular methods, including the 'post-tension coupling method.'
A key differentiator of this technology is the 'reverse slope clip' structure, designed to prevent water penetration at the joints between materials. This innovation reduces the risk of cracks, mold, and contamination that can occur with traditional silicone or grout methods, while also improving maintenance convenience.
According to DL E&C, this new technology combines its construction expertise with Hansol Home Deco's finishing material technology. It is currently being applied in housing brands such as Acro and e-Pyeonhansesang. This development has reportedly increased productivity by about three times compared to previous methods and reduced defect rates on-site by over 60%. Labor input has also been cut by approximately 18%.
A DL E&C representative stated, "This new technology revolutionizes bathroom construction productivity and fundamentally addresses chronic issues such as tile detachment and cracking. We will continue to lead the industry by overcoming the limitations and challenges of existing methods."
Meanwhile, industry experts anticipate that demand for dry bathroom systems, which can shorten construction periods, will grow alongside the expansion of the remodeling market for aging apartments.
