The waterproof current situation of construction engineering in China is not optimistic. Statistics once done by China Building Waterproofing Association show that the leakage rate of underground construction projects in China is as high as 80%. Leaks from underground waterproofing works are even called the "cancer" of buildings.

The quality problem of construction engineering is a system engineering, but also a social engineering. The leakage of construction underground engineering will inevitably affect the quality and safety of construction. We should attach great importance to the underground leakage and construction engineering quality problems, explore the solution path to block the underground leakage from the root cause, effectively improve the quality of construction engineering, and ensure the safety of construction.

For a long time, the society has paid more attention to building underground waterproof engineering far from enough, people lack of understanding of the complexity and comprehensive nature of underground engineering waterproof technology, think that leakage has little impact on the safety of the structure, and do not analyze the groundwater environment law of the built engineering, which is a common misunderstanding.

In the design and construction of the waterproof engineering simplified treatment, the lack of effective waterproof scheme design and improper material selection, construction methods, resulting in some problems in the engineering construction, frequent leakage. In the past, leakage was thought to have little impact on the structure, but the opposite was true.

With the emergence of leakage, the invasion of water, carbon dioxide, acid and alkali medium and so on in the leakage channel will accelerate the corrosion of steel bars, crack collapse, and then lead to the decline in structural safety, construction safety accidents occur from time to time.

"Underground engineering waterproof technical specifications" GB 50108-2008 clearly said: "the building underground waterproof is mainly divided into two parts, one is the main structure waterproof, the second is the fine structure waterproof". The main body of the structure should be the basis of underground waterproof work, and the waterproof structure is in an auxiliary position.

However, the reality is that the structure of the waterproof "quietly stealth", attached to the outside of the structure of the external waterproof layer "overwhelming", the importance of the main body of the structure waterproof is ignored.

Therefore, the traditional concept must be changed: no longer put the underground waterproof engineering in the second only position of the structure, but to promote the building underground waterproof engineering to the same important height as the structural engineering, so as to ensure the effectiveness of waterproof engineering, ensure the building quality and safety, extend the life cycle of the building.

The general view of the industry is that: to do a good job of building underground waterproof, we must return to the fundamental —— structure of building underground waterproof self-waterproof.

As the saying goes, "If you want to work for a long time, internal service + external use."In the building waterproof industry, especially in the building underground waterproof, this sentence is still applicable, want to solve the building leakage problem to be solved, do a good job of building underground waterproof, maintenance of building quality and safety, it is necessary to apply the right medicine: "internal service" and "external use", internal and external double prevention, it is more effective!

The permeable crystalline structure self-waterproof technology system launched by GUARDEX constructs dual protection by mixing SJ series self-healing inorganic proliferation waterproof agent and external spraying SK series nano-silicon ion permeable modifying agent from the inside out.

SJ series of self-healing inorganic proliferation waterproof agent for concrete (internal) mixed waterproof material, containing amorphous active silicon and water, cement, calcium hydroxide reaction, calcium silicate crystal, large Angle, large area of reproduction filling concrete internal pores, micro cracks, improve density, and heal cracks, and permanent waterproof moisture-proof impermeability, also can greatly extend the life of concrete.

SK series nano silicon ion immersion agent for concrete (external) spray material, can deeply penetrate into the concrete internal 30-50mm chemical reaction, generate calcium silicate crystals fully filled to the concrete internal pores and fine cracks, make concrete compactness better, so as to inhibit the production of concrete cracks, improve the waterproof level, cut off the seepage channel, fundamentally solve the problem of building water leakage.

SJ series + SK series combination application, both deep inside the concrete, activate the concrete crack since healing performance, from the internal healing capillary pores, micro cracks, and in the concrete structure surface plugging pores, cracks, at the same time formed with the structure with the life of the waterproof layer, internal and external combination, double protection, realize with the building life of waterproof protection effect!

Compared with the traditional waterproof method, GUARDEX structure self-waterproof technology has the advantages of convenient construction and operation, saving construction period, cost and cost, safe and efficient and low carbon and environmental protection, and the effect is deep into the concrete interior, the concrete durability, crack resistance and corrosion resistance can be significantly improved, so that the concrete life is extended by 1-2 times.

GUARDEX structure self-waterproof technology, internal and external double defense, for the building underground engineering to provide scientific and perfect waterproof solutions, in line with the requirements of technical specifications, design requirements and actual use needs, from the root to solve the waterproof problem, comprehensively improve the quality of construction engineering, for the construction safety of the escort.

Building underground waterproof engineering and building underground structure, foundation concrete quality in the same, closely related.Therefore, for building underground leakage, we should jump out of the traditional waterproof cognition, stand in the height of "building quality" and "building safety" to understand this problem, start from improving the comprehensive durability of concrete, comprehensive protection of concrete, prolong the life cycle of the building, protect the safety of the building structure.
