Product Description:

Non-explosive Demolition Agent

NDA is a soundless and safe demolition agent which is quite different from ordinary demolition agents such as explosives and dangerous materials. It does not cause any fly rock, noise, ground vibration, gas, dust or any other environmental pollution when used properly.
As requirements for cracking the stone and demolishing rock and reinforced concrete in construction increase in tight quarters, the use of explosives and explosive agents is becoming more restricted as far as safety and environmental pollution problems are concerned.NDA is the best solution.

• Granite, marble, sandstone, limestone, quartzite quarrying.
• Rocks pre-splitting, fracture, cutting, demolishing and removal.
• Controlled demolition or cutting concrete.
• Fracture and demolition of the concrete buildings and structures.
• Excavation of trenches and foundations.
• Underground excavation and removing boulders.
• Marine excavation including underwater operations

• Amazing Expansive Capability
Amazing expanding capabilities breaks reinforced concrete, rock, marble, granite, limestone or any material you are working with. Depending on the material you are working on.
• Easy to use
No formal training required before use. Just mix with water and then fill into holes. Once mixed with clean water, CRACK.AG can be poured into holes pre-drilled in the material you are working with It can be poured into the same holes that dangerous explosives are usually placed in.
• Non-Explosive Environmentally Friendly
Much safer than explosives, with NO Noise, NO Vibration, NO Flying Rocks and NO Toxic Gases.
• Works Efficiently and Cost Effectively
No Special License, training or equipment needed.

Depending on temperature, there are three types.

SCA Types

Temperature (Celsius)


25 - 40 degree C


10 - 30 degree C


-5 - 15 degree C

Package & Storage
40 kg paper-plastic bag package.
1. Although NDA is packed in anti-moisture paper bags, long storage may cause deterioration of its working ingredients. Therefore, store in a dry place and use it as soon as possible.
2. When storing, do not place the bags of NDA directly on floor, put them on a pallet and keep in a dry warehouse etc. NDA stored in this manner, can be effectively used for about 1 year.
3. MDA should be unpacked before use.
4. When storing the portion of NDA remaining after use, push the air out of the bag, then seal with gum tape and use as soon as possible. However, as it may get exposed to moisture there is a risk of NDA losing its effectiveness once the bag has been opened.
5. If you receive broken bags of NDA, they may not work due to chance of moisture absorption.

Q:Why is the waterproof material divided into rigid and flexible? Which is better than that?
The material is divided into rigid and flexible according to its characteristics. Rigid waterproof material generally refers to the cement mortar, in its formation of waterproof layer, has a high resistance to pressure, impermeability, but does not have the extension, resistance to structural elongation change ability is not high. The flexible material has good elasticity and plasticity, and the extensibility can adapt to the slight deformation of the structure. See where you use, and if used in home decoration, should be flexible waterproof material as the main material of the construction.
Q:Who knows the inorganic insulation mortar and the previous material What is the difference?
Good durability, good weatherability good hydrophobicity, strong vapor permeability high refractory grade, non-combustible good adaptability, easy construction, Speed, a comprehensive technology, practice diversity green, non-polluting, non-radiation ecological building materials Disadvantages: the current implementation of the standard is GB-2006 "building insulation mortar", this standard is the material standard, there is no specific system standards.
Q:Basement wall wipe 20 thick PG waterproof mortar, what is "PG waterproof mortar"?
Definition: the so-called refers to the cement mortar mixed with a variety of waterproofing agent prepared by a class of new waterproof building materials products; usually joined the waterproofing agent is a variety of inorganic or organic chemical raw materials consisting of admixtures, Can improve the mortar impermeable, so the name was born
Q:According to the different parts of the building, how to choose mortar mortar?
the middle is mainly to leveling, and sometimes can be omitted do not do
Q:Waterproof engineering should be arranged at what time to do the best?
If it is civil engineering to be completed after the main body, naturally dry, can be carried out! If it is decoration works, as long as the start can be carried out, the sooner the better, so that cross with other processes, resulting in problems!
Q:What waterproof material can be combined with cement mortar to play a waterproof effect?
If the use of flexible waterproof coating to do the bottom, the flexible features of the tensile effect is also good waterproof, mortar waterproof waterproof surface to do, both play a waterproof and protection to serve two purposes
Q:Waterproof wall how to deal with better? What is the general material?
I have done this friend, if the sticky tiles, may not apply, because the car wash when the bumps, if the sticky tiles do not need to do waterproof, that tiles is waterproof, as long as the tile gap with tiles to deal with like , It is recommended that you still do cement mortar waterproof method is to use the new green high concentration mortar waterproofing agent, against the concrete inside the sand, and then wipe a layer of gray on the wall ok. If you use other products, it is easy to cause wall cement layer off,
Q:Rural brick and concrete room can do external wall insulation, what materials and practices inexpensive?
External thermal insulation materials are only affordable with rock wool board
Q:Polystyrene insulation mortar insulation in the external walls. Foreground will be how,
Polystyrene particles insulation mortar market prospects, not very optimistic. The reasons are: 1 now the state of the external wall insulation materials, the level of fire requirements are getting higher, and polystyrene particles fire level can only reach B1 level. 2 glass beads and the appearance of active inorganic mortar will greatly reduce the market share of polystyrene particles, vitrified microbeads and non-polar sand scrambled jar waste Intuit Biao Shizha lotus pulp are A-class fire and easy construction The
Q:Do the wall waterproofing can be directly on the brick brush on a layer of waterproof material on it
Can be ah, but in general are rafting spoiled slander diarrhea oblique riveting is done on the concrete, in fact, there are some tiles waterproof role, the late seepage of the words will be outside the brush waterproof paint, are generally used transparent glue, recommended Dragon wall waterproof transparent plastic, before the seepage used to the past few years will not change color, does not affect the decorative effect.
