The return of the basements of the old sub-districts of the water permeation problem and the opening of the new balconies to the balconies have become a real problem for many owners. Water-proofing projects have been in place for many years, focusing on the leakage scenes of this type of structure and the environment, rather than on general theory, and addressing only the humid traces that are visible and felt。
The basement wall keeps coming back? The roots are often in the tectonic layers
Part of the old sub-surface space in the depressed mountains does not contain a complete flood-proof layer, or the old rolls fail to function, resulting in soil fine water moving along the micro-pore of concrete, exposed at wall corners, kick-and-foot lines, peeling, and alkaline. Pure waterproof coating of surfaces does not block water and steam passages. The water-proofing project uses pressure-plugging in combination with a rigid interior anti-water-slurry composite process to block the permeable water path from the interior of the structure and is designed with a ventilation dehumid node to restore dry and stable surfaces。
The balcony leaks more than the bricks loose
Many owners find that the drain is slow after the balcony has accumulated, which leads them to assume that the sewers are blocked; more often than not, structural cracks caused by the fall of the building, or waterproof intakes at the docks interface with the floor, fail. Rain water permeates below this suture and flows through the inner cavity of the wall to the roof of the floor, forming a hidden leak point “upgrade dripping, bottom wet”. The hydrocrystalization project locates leakage through infrared thermal imaging, removes the original waterproofing layer from the structural base, re-paints soft waterproofing rolls and strengthens the additional layers of the diaphragm to ensure full and uninterrupted water stress release at the seams。
Material selection to fit the climate characteristics of gangnam
Hangzhou is characterized by high humidity and frequent variations in temperature, with general waterproofing materials that can be powdered, drummed or stripped from the grass roots. The polymer concrete-based waterproof coating used in the water-proofing project has good aerobic and adhesive force, while the scrolls select a root-plugged modified asphalt product that combines anti-aging and anti-conformity. All materials are selected according to the function of the construction area, with no stacking of parameters and a repertoire of service performance。
Reduced residential impact of maintenance processes
The basement operation avoids the peak hours of daily activity of the residents and the construction of the balcony is conducted using dry dry interfaces and sub-seasonal tests to avoid the complete layer being decommissioned for several days. Control of dust proliferation during the removal of old layers, after repairing the ground level by an error of less than 2 mm, and with the possibility of a tile re-painting directly to the pre-past, without the need to raise the threshold or adjust the doors。
There's proof of completion
A 48-hour water-storage test is conducted before each service is completed, the balcony is focused on the perimeter and anti-canne, and the basement is focused on the wall roots and the equipment tube. The results are archived in live video records, seepage points are eliminated, grass-roots drying is not unusual and do not use the criterion of “surface non-dropping”。
Long-term effects come from detail control
Waterproof life depends not only on materials, but also on whether nodal treatment, such as balcony discharge slopes, pre-positioning of water belts, and double-assembled polyurethane sealing through walls. In the course of the work, the water-proofing project examines each of these easily neglected construction requirements and converts the normative provisions into tactile process actions。
The problem of water penetration has never been isolated, and it links the length of construction, geological conditions, construction quality and usage habits. In the face of retort and balconies that are common in the depressed mountain region, the water-proofing project is not standardized but customised on the basis of field measurements of data and structural characteristics. Each patch is a response to the real state of the house。
