CHM is the result of a lifelong business, marked by the dedication of a well done work over two generations. Since our origins, construction in all its variants has been our daily activity and the continuous improvement, our objective.

Our company is part of the Vallalba Group: an example of constancy and competitive capacity which, with the purpose of ensuring quality at every stage, has been integrating specialized companies.

CHM has grown to become a reference in the construction sector at a national level, diversifying our client portfolios as well as our project portfolios. Our initial specialization and the execution of roads and communication ways have created a company able to take on any public or private projects anywhere. In order to do so, we count with a number of branches where we give the best services to our clients as well as our suppliers. We are not restricted to our national sphere as we are carrying out at present projects in Poland and finalized important agreements with Middle East countries with our branch in Abu-Dhabi (UAE). We have also carried out projects in Morocco.
