DL E&C has accelerated productivity and quality innovation in bathroom construction by obtaining construction technology certification from the Ministry of Land, Infrastructure and Transport for its dry wall waterproofing system.
On October 13, DL E&C announced that its 'Dry Wall Waterproofing System for Bathrooms,' developed in collaboration with Hansol Home Deco, received certification from the Ministry of Land, Infrastructure and Transport. This certification is awarded to newly developed technologies or improvements to existing technologies that demonstrate novelty, advancement, and applicability on-site.
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 wet method that requires separate waterproofing and curing processes, leading to longer construction times and a need for skilled labor.
In contrast, DL E&C's dry construction method involves attaching 16 large panels (2440×590mm) with waterproofing capabilities to a lightweight wall structure of approximately 16.3 square meters. This eliminates the need for a curing process, thereby shortening construction time and enhancing efficiency.
Notably, this technology is considered similar to the box-type modular construction methods that are gaining traction in the industry. Bathrooms, traditionally seen as wet spaces requiring waterproofing and tile installation, can now benefit from standardized construction and simplified processes through the introduction of the dry system. Previously, DL E&C secured foundational technologies related to box-type modular methods, including the 'post-tensioning coupling method.'
A key differentiating feature of this technology is the 'reverse slope clip' structure, designed to prevent water penetration at the joints between materials. This reduces the likelihood 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 was developed by combining its construction expertise with Hansol Home Deco's finishing material technology. It is currently being applied at sites for its housing brands, Acro and e-Pyeonhansesang. This innovation has increased productivity by approximately three times compared to previous methods and reduced defect rates on-site by over 60%. Labor input has also been cut by about 18%.
A DL E&C representative stated, “This new technology revolutionizes bathroom construction productivity and fundamentally addresses chronic defects such as tile detachment and cracking. We will continue to lead the industry by solving the limitations and challenges of existing methods.”
Meanwhile, industry experts anticipate that demand for dry bathroom systems will increase alongside the expansion of the remodeling market for aging apartments, as these systems can significantly reduce construction time.
