Dynamic Foundation Engineering

SERVICES

Our interventions achieve the restoration of dynamic stability

We ensure mechanical reliability, preventing breakdowns, and increasing equipment lifespan, operational efficiency, and safety.

Our solutions are meticulously designed to deliver cost and time savings for our clients, ensuring optimal performance and longevity of their equipment.

With a focus on dynamic equipment, on-site repairs, and our proprietary epoxy grout, we have successfully completed over 4,000 projects for leading companies in sectors such as Petrochemicals, Refining, Steel, and Fertilizers.

Our extensive experience encompasses a wide range of machinery, including compressors, hypercompressors, diesel engines, electric motors, pumps, reducers, blowers, turbines... Ultimately, we can and have experience in repairing and enhancing the foundations of any dynamic or static equipment

Irrespective of the base material, whether it's metal plates, racks, or direct foundation applications, Apoltec offers tailored strategies that comply with international regulations, setting industry standards.

There are several symptoms revealing an incipient damping system fatigue, for instance:

Cracks induced by thermal and mechanical stress.

Oil penetration that counteracts friction response against lateral movement or detaches grout from machine footprint, anchor bolts or foundation.
Corrosion of peripheral rebar, anchor bolts or bed frame surfaces that affects alignment and vibration isolation response.
Cold or construction joints separation that discontinues foundations as a continuous mass behaving as undersized dampener.
Shear stress on anchor bolts or loss of stretching and torque.
Air gaps underneath mounting frames where oil can be drawn in or to allow resonance
Subsoil differential settlement which may increase rocking movement.

Our approach

Our comprehensive approach encompasses the entire project lifecycle, from meticulous technical analysis to precise execution. Whether it’s dynamic or static machinery, we ensure optimal performance and longevity, adhering to the highest international standards as API686, EFRC, ASCE, ACI, ISO, ASTM. BSI, EHE…

In the event of a stability issue arising from degraded grout due to oil and vibration, Apoltec offers a solution to replace the existing grout without the need to remove the equipment, saving time and complications for the end-user.

About the damping system, is essential to effectively absorb and attenuate the residual mechanical energy of the machine, transferring it to the subsoil in the form of a natural spring.

Our specialty is optimizing the damping system, from the bed frame to the subsoil, eliminating unwanted vibrations, repetitive misalignments, poorly grouted areas, corrosion, damaged bolts… In essence, the restauration of dynamic foundations damping ability that have a direct impact on the equipment.

A standard damping system comprehends:

Base Frame, which is consider the highest rigid structure being part of the machine case or not (mounting frame, skid, sole plates, rails, …). It’s hold down to the foundation thru the anchoring system.
Anchoring system performs as device for displacement restrain and is critical for modifying the tensional state of underlying materials in order to better resist fatigue.
Grout is a layer that connects machine to the main foundation inertia block and has an essential damping and inertia restrain duty.
Foundation, in the way of mat or slab, base rafts, columns, pillars, plinths, inertia blocks, and so on, lowers gravity center, increases and adds inertia mass to the machine, dampers vibrations, and compress under pressure subsoil materials.
Subsoil, as a natural spring for energy dissipation. It is tuned on phase by all elements above.

Epoxy Grouting for Reciprocating Compressor Foundations

Specialized epoxy grouting for reciprocating compressor foundations in oil & gas and petrochemical plants. API & EFRC-compliant, 25+ years of experience, lifetime warranty.

Reciprocating compressors generate intense cyclic loads and vibration that ordinary cementitious grout cannot withstand over time. At Apoltec, we specialize in epoxy grouting systems specifically engineered for reciprocating compressor foundations, following API and EFRC (European Forum Reciprocating Compressors) guidelines for foundation design, anchor bolting, and grout performance.

Our epoxy grouting solutions provide superior load transmission, vibration damping, and chemical resistance — critical in aggressive petrochemical and oil & gas environments where foundations are exposed to hydrocarbons, high temperatures, and continuous dynamic stress. We have applied this expertise across more than 200 projects for operators including Shell, BP, Repsol, and SABIC.

Whether your compressor foundation shows early signs of cracking, base plate movement, or grout deterioration, our technical team can diagnose the root cause and deliver a turnkey epoxy regrouting solution — on-site or with equipment reinstallation — backed by a lifetime service guarantee.

EQUIPMENT FOUNDATION REPAIR PROCESS

1. Technical Analysis and Inspection

We conduct a thorough physical assessment and analysis to prepare the technical project and security plan.

2. Product Design and Selection

Based on climatic and chemical factors, we select the most suitable Apoltec products to achieve project goals.

3. Design and Manufacture of Support Frames

Our engineering team designs and manufactures frames to support machinery if necessary.

4. Demolition of Equipment Foundation

We remove the surface of the original base and re-foundation unrecoverable points.

5. Epoxy Injection and Crack Repairs

Utilizing our Apoltec 370 resin, we perform highpressure injection to consolidate the bench and extract filtered residues, ensuring adhesion on oil-contaminated surfaces.
