A Word from the Customer


Arnel Arawiran

Quantity Surveyor, L&S Developments

The construction of a ramp structure is always challenging concerning constructability, safety, and cost. This is on top of a lot of adjustments needed to be done to achieve the required slope of the ramp. The above type of construction always incurred a higher cost.

KORE insulation tick all the boxes with regards to addressing all the above issues. It is safe and easy to install, cost-effective, and structurally adequate, as well as offering a variety of sizes and shapes.

About the Merrion Road Hotel & Residential Project

The Merrion Road hotel and residential project is currently underway at the location of old Tara Towers Hotel, Merrion Road, Dublin 4.

The development is comprised of demolishing the existing building and constructing a new structural concrete frame building of a 9-storey hotel and 7-storey residential development on top of a single storey basement. The basement and ground floor will serve as a Carpark that will be accessed by a ramp through Ascaill Bellevue.

This project is delivered by L&S Developments as the main sub contractor.

Merrion Road Technical Drawing

KORE Void Formers and Customised Specification

L&S Developments, a construction firm, chose KORE Void Formers for the Merrion Road project due to the ability of KORE to manufacture a void former ramp to the exact specifications needed for the basement.

L&S Development chose KORE EPS100 White Void Formers, enabling a cast in situ ramp to be formed from the ground floor to the floor below. To achieve milimeter accuracy and the required specification of the slope and radius, KORE manufactured 50 individual pieces of varying size and shape, allowing the ramp from ground floor to the basement cast between radius walls. Another benefit with EPS is that concrete can be poured directly onto it without the need for a DPM separation layer. The long term physical performance of EPS also makes it a natural choice with defined compressive strength.

EPS is a very well suited product for this application and can be profiled and cut in the factory to match the site specifics. In the case of Merrion Road, the EPS was cut to follow the slope of the ramp on site. Using EPS void formers solved the issue faced when dealing with infill existing sites which can challenge a contractor. As the EPS void formers are lightweight, they are easily placed on site without the need for machinery and quickly too, creating a temporary formwork to facilitate works. The voids required precision accuracy down to the millimeter, as the project was very precise with high specifications including radius layouts and void radius up to 1200mm.
