Soundproofing in Azimut Complex Burgas - German KRAIBURG Relastec Technology

This article has been updated 25 07 2026


Why noise insulation is a necessity, not a luxury

Anyone who has lived in an apartment building knows: footsteps from upstairs neighbours, lift humming, children's laughter from the playground - all become part of daily reality. But does it have to be this way?

At Azimut Complex in Burgas, the project's creators solved this radically - using advanced German soundproofing technology from KRAIBURG Relastec. The project implements over 500,000 m2 of vibro- and sound insulation solutions - a scale that places Azimut alongside Europe's finest real estate developments. Previously, this level of acoustic comfort did not exist in Bulgaria.


Who are KRAIBURG Relastec and why they were chosen for Azimut

KRAIBURG Relastec's production facilities are located in Salzwedel, Eastern Germany (near Berlin). The company specialises in sound and vibration insulation products supplied worldwide. Their clients include major hotels in Dubai, Australia and other countries. They are world leaders in acoustic solutions for construction.

DAMTEC multi: universal floor noise insulation solution

The foundation of sound insulation in Azimut apartments is DAMTEC multi - KRAIBURG Relastec's flagship product. This is a universal sound insulation under screed used on staircases, in living areas, and under walls.

How DAMTEC multi works: mats are laid under the screed - the most effective solution for protecting against impact noise. When walking, vibrations occur that transfer through floors to neighbours. DAMTEC multi absorbs these vibrations, preventing sound from spreading. The main advantage: you won't hear footsteps from upstairs neighbours.

Why thickness is not the main factor: KRAIBURG Relastec's laboratory tests show that a thicker product does not always deliver better results on the delta LW index. For Azimut, the optimal material type was selected - the ideal price-to-performance ratio.

Multifunctionality: the material is used as continuous coverage under screed (impact noise protection) and as strips under walls (partition vibro-insulation). This approach simplifies installation and guarantees a uniform quality standard.


Lift shaft and commercial zone soundproofing

Azimut includes not only residential apartments but also commercial spaces: restaurants, cafes, beauty salons. Additionally, lifts are installed - a source of both vibration and airborne noise.

A comprehensive approach is applied to such zones:

✓ Noise type separation - impact (footsteps) and airborne (voices, music, lift)
✓ "Box-in-box" system - floor, wall and ceiling insulation of lift shafts
✓ Materials at 1,020 kg/m3 - high density for airborne noise absorption
✓ Result - residents don't hear lift humming, restaurants don't disturb residents


Playground and sports area surfaces

Children's playgrounds - EPDM surfaces Euroflex and Sportec:

✓ Resistant to all weather conditions - sun in summer and cold in winter
✓ Durable - do not fade or crack over the years
✓ Safe - softness on impact, available in various colours

Sports zones:

✓ Fitness halls - amortisation and vibration absorption
✓ Tennis courts - optimal grip and ball bounce
✓ Football pitches - durability under intensive loads

The base consists of rubber crumb and recycled granules. This delivers not only high technical performance but also eco-friendliness.

 Key difference from mass-market solutions

KRAIBURG Relastec stands out with a critically important advantage: high efficiency at low thickness.

Why thick insulation is a risk:

✗ Risk of cracks in screed and tiles due to excessive softness
✗ Loss of room height - critical for modern apartments
✗ Additional load on floor structures

Why the German solution is reliable:

✓ Maintain properties for decades without degradation
✓ Do not require thick layers - save space
✓ Verified by on-site measurements after installation

 Quality control: how soundproofing is checked after installation

Quality is verified through on-site measurements after installation by a certified specialised firm. When installation is performed correctly, measurements confirm the declared performance. These are not promises on paper - this is a verifiable result.


Azimut Burgas: the first project of this level in Bulgaria

Azimut is the first and only project in Burgas with such a comprehensive approach to soundproofing. KRAIBURG Relastec technologies are applied:

✓ Under screed - in residential apartments (DAMTEC multi)
✓ Above screed - in finish coverings
✓ Between double walls - partition vibro-insulation
✓ In lift shafts - "box-in-box" system
✓ On playgrounds - EPDM Euroflex/Sportec surfaces
✓ In sports zones - individual solutions

This is a completely different level of European construction, previously unavailable in Bulgaria.


Eco-friendliness and durability: recycled materials at the core

Surfaces for sports and children's zones are manufactured using high-tech recycled materials (recycled rubber granules). This reduces waste volume, preserves natural resources, and ensures durability without quality loss. Azimut is not only about comfort but also environmental responsibility.

❓ Frequently asked questions

❓ What is DAMTEC multi?

DAMTEC multi is a universal sound insulation under screed from the German company KRAIBURG Relastec. Mats are laid under screed and absorb impact noise (footsteps, falls), preventing vibrations from transferring to neighbours below.

❓ Why is thin insulation better than thick?

KRAIBURG Relastec laboratory tests have proven: a thicker material is not always more effective. Thick insulation creates risk of cracks in screed, reduces room height, and increases load on floors. German materials deliver high acoustic performance at optimal thickness.

❓ How is soundproofing quality verified?

Quality is verified by on-site measurements after installation by a certified firm. Measurements show real acoustic performance - not promises on paper, but a verifiable result.

❓ What is the "box-in-box" system?

A comprehensive insulation system for lift shafts and commercial zones where floor, walls and ceiling are insulated using materials with high density (1,020 kg/m3). Residents don't hear lift humming.

❓ Why is Azimut the first such project in Bulgaria?

Previously, Bulgaria had no projects with this scale of German acoustic technology application - over 500,000 m2 of insulation under screed, in lift shafts, and on playgrounds.

❓ What surface is used on children's playgrounds?

EPDM surfaces from the Euroflex and Sportec lines - weather-resistant, durable, safe on impact, available in various colours.
