Louhintaliike Ylimäki Oy, headquartered in Lapua, is a family business that specialises in large-scale blasting and quarrying operations covering the areas of Pirkanmaa, Western and Central Finland and North Ostrobothnia. With more than 40 years of experience in the industry, the company guarantees its customers efficient and flexible service, helping it become one of the biggest quarrying operators in Finland.
Aatos Ylimäki founded Louhintaliike Ylimäki Oy in 1983. The company started out with rented equipment, but soon acquired its own manual drill and tractor-mounted air compressor. The company’s first contract was foundation work for a vocational school (Hervannan ammattiopilaitos) in Tampere. Over the years, the company’s fleet of equipment and number of personnel has grown. In 2012, the family company was transferred to the next generation, and since 2015 it has been headed by Matti Ylimäki.

According to Managing Director Matti Ylimäki (centre), head charger Matti Pitkäjärvi and driller Markku Viitanen, Louhintaliike Ylimäki has relied on the quality of Robit’s consumables, such as drill bits, rods and shanks, in its drilling operations for more than 20 years.
Quarrying with a large capacity
Today, Louhintaliike Ylimäki is known for carrying out large-scale blasting operations. With a staff of 20 and a fleet of 18 machines, the company performs rock extractions amounting to 7 million tonnes a year in a range of sites.
“Among our customers are aggregate suppliers, crushing companies and earthworks companies. We blast rock in open-pit mines in roughly 70 different sites every year; in recent years, we have also carried out a number of contracts for wind farms. We have numerous long-term customer relationships, which helps us in planning our operations in advance. Our services include crushing extractions and other large-scale quarrying, excavation of building foundations and road alignments, rock-breaking using a hydraulic rock hammer, per-metre drilling, rock slope scanning and hole straightness measuring,” lists Managing Director and head charger Matti Ylimäki.
Top-notch machine performance
Louhintaliike Ylimäki’s fleet of drilling equipment consists of six mid-range Sandvik drill rigs for open-pit mining and two Doosan excavators equipped with an ExcaDrill rock drilling attachment. The company also extensively uses rock-breaking equipment: 14 primarily Atlas Copco rock hammers mounted on ten 30–35-tonne excavators, most of which are from Doosan’s range. A wide array of other equipment used in quarrying contracts, from dumpers to vibration meters, is also in the company’s fleet.
Drill rigs are replaced after roughly 5 to 6 years of use; in one year, a single rig drills around 60 to 70 kilometres of holes in rock. The equipment is maintained at our own workshop in Lapua and of course we also use the equipment supplier’s maintenance services,” says Ylimäki.
Decades of co-operation with Robit Louhintaliike Ylimäki has relied on the quality of Robit’s consumables, such as drill bits, rods and shanks, in its drilling operations for more than 20 years. “Robit is a very important partner to us. As a Finnish operator, their service and products are always nearby, they listen closely to customer feedback, and perhaps most importantly for an operator of our size, their service is flexible – Sales Manager Esa-Matti Polvi is very pro-active, always on the lookout for new solutions to further enhance our operations. And of course the products are in top condition, which enables efficient drilling and well as a good price/quality ratio. Robit’s continuous product development brings better solutions to market and if we need, say, a few dozen special bits, they will be produced in Lempäälä just the way we want them and on a tight schedule,” praises Ylimäki.
A container with drilling products on site
A year ago, Robit set up a consignment stock at Louhintaliike Ylimäki’s location in Lapua.
“The products stocked in the container include all the drilling consumables we need, meaning bits, rods and shanks, as well as coupling sleeves and bit adapters, to name a few. Robit invoices us for the products we use, and we place orders to ensure the shelves are always stocked with what we need. The container itself was made to be user-friendly, so picking products and, for instance, using a forklift to lift drill rods onto the rack is easy. Drillers bring the products to the worksite with them in their vehicles, and they always have enough for one or two weeks’ worth of work on the rig,” says infrastructure engineer and head charger Matti Pitkäjärvi.
Robit’s consignment stock has significantly improved Louhintaliike Ylimäki’s logistics:
“It makes things easier for drillers when they can pick up the consumables they need from a single location straight off the shelf, without having to order them separately,” says Pitkäjärvi.
