Dynamic Foundation Engineering
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 dampening 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 dampening 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 dampening 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.
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.
6. Anchor Bolt Removal and Replacement
Apoltec offers solutions for anchor bolt breakage, providing design and installation services for anchor bolts of all sizes.
7. Hydraulic Pad Lift
We utilize hydraulic pads to sustain machinery and facilitate leveling, avoiding "hard spots."
8. Machine Leveling
Our team analyzes and corrects any deviations of the machine with respect to alignment points using dial gauges and meters.
9. Formwork Design and Manufacturing
We design and manufacture formwork according to grouting location and requirements.
10. Machine Grouting
With over 25 years of experience, we expertly grout heavy machinery, selecting the best method based on equipment placement and frame.
