Grouting

What is grouting?

The chocking or sealing of an object using Grout.

Grout is a ready-to-use mixture of ingredients composed of a base, a hardener, and aggregates.

Grout ensures perfect contact between machinery, rail, skid, pump, or any other metallic object and its foundation.

According to API 686, grout provides uniform support and perfect load transfer between the sealed object and its foundation.

What are the types of grouting?

The most common is cementitious grouting. A simple solution, based on cement mixed with water and additives, it offers the advantage of its simplicity. Its main disadvantages are a low compressive strength and a very high modulus of elasticity, which makes it less suitable for vibration absorption. Additionally, it requires a longer curing time, and there is a risk during preparation due to on-site water dosage.

Alternatively, you have the epoxy system or CHOCKFAST, composed of a resin, a hardener, and aggregates. The advantages of CHOCKFAST are numerous. Among other things, it offers a rapid polymerization time, reducing downtime; it has no shrinkage; it exhibits high compressive strength and a very low modulus of elasticity, allowing for excellent vibration resistance and ensuring alignment over time.

Chockfast

Concrete

Compressive strength

105.5 MPa – 131 MPa

20.7 MPa – 41.4 MPa

Tensile strength

13 MPa – 32.3 MPa

2.8 MPa – 4.1 MPa

No shrinkage in liquid and polymerized phases. Resistant to most liquids, chemicals, oils, greases, and seawater.

Shrinkage in liquid and hardened phases depending on environmental conditions. Exhibits much less resistance to several of these products.

The advantages of Chockfast grouting are:

A highly attractive price/lifespan ratio
No shrinkage
A compressive strength between 850 and 1,300 kg/cm² (85 and 130 N/mm²)
A very low modulus of elasticity
Vibration absorption
Easy to mix as it is pre-dosed
Rapid polymerization time with the advantage of very short downtime (18 to 36 hours)
Resistant to chemical corrosion
Perfect compatibility with steel and concrete
Pouring thicknesses ranging from 10 to 500 mm (depending on product variants)
Friction coefficient 4.5 times higher than that of concrete
Ensures alignment over time

"In order to fill 3 compressor skids, with approximately 34,000 kg each, with epoxy grout and also the frame with cement grout, we were looking for a flexible partner who was willing to take on this challenge that included lifting the 3 compressors to allow concrete surface preparation. The area to be covered had an irregular shape and a variable height. Finres managed to execute the work on time quickly & smoothly. Because a lot of attention was paid to determining the correct approach and the work preparation, we are extremely satisfied with the cooperation with Finres and with the end result for this complex assignment."

"Following a request from SEGAL for the repair of the seat of a rail coil lift truck (capacity 30 tons), we agreed with Mr. Scheppers on an action plan to meet the requirements of the specifications. After the SEGAL purchase process, FINRES was ready to start the necessary actions according to the production schedule. On the day, the FINRES and SEGAL teams worked together to meet the deadlines set by SEGAL. Following this joint intervention, we were able to test the operation of the said loading trolley and conclude that the work carried out was a good job. If in the future I am consulted for a similar type of work, it is with pleasure that I will recommend the company FINRES for its competence, professionalism and availability."

"In order to fill a 10 m² area between our mechanical parts and a 2,000-tonne steel structure, we were looking for a flexible partner who was willing to take on this challenge. The area to be covered had an irregular shape and a variable height. Finres managed to come up with an out-of-the-box solution that was also executed very quickly & smoothly. Because a lot of attention was paid to determining the correct approach and the work preparation, we are extremely satisfied with the cooperation for this complex assignment."

"We have had a great experience working with Finres on a railway bridge refurbishment project. The preparation of the works was done on time and with a good dose of common sense and practical knowledge. Experience of working with these specialized grouting products was evident and proved essential for the success of the project. The flexibility in planning on site and the safe working practices was greatly appreciated and led to a productive cooperation on site."
